Normal Consistency of Hydraulic Cement | Jameel AcademyJameel Academy
This report summarizes a test to determine the normal consistency of hydraulic cement. Four trials were conducted with 500g of cement and varying water-cement (W/C) ratios of 0.25, 0.27, 0.30 and 0.33. These trials resulted in penetrations of 25mm, 9mm, 5mm and 4mm respectively. From the relationship between W/C ratio and penetration, the standard consistency was determined to be 0.2875 at a penetration of 6mm. However, the average penetration of 10.75mm exceeded the standard of 6±1mm, suggesting errors in the test such as insufficient cement quantity and inaccurate penetration measurement timing.

Method for determination of shear strength of soil (Badarpur Sand) with a maximum particle size of 4.75 mm in drained conditions using Direct Shear Test apparatus.
It is a Floating Box type test in which upper half box is floating due to application of vertical loading resulting in lateral confinement thus generating sufficient friction which holds the upper half of shear box.
In the shear box test, the specimen is not failing along its weakest plane but along a predetermined or induced failure plane i.e. horizontal plane separating the two halves of the shear box. This is the main drawback of this test.
Moreover, during loading, the state of stress cannot be evaluated. It can be evaluated only at failure condition. Also, failure is progressive.

The document describes procedures for determining the liquid limit and plastic limit of soil samples.

These limits are used to classify soils and predict properties like strength and compressibility. The plasticity index, defined as the liquid limit minus the plastic limit, provides further information on soil type and reactivity. Proper determination of the Atterberg limits is important for building foundations to ensure suitable shear strength and volume change with moisture fluctuations.

Introduction
Grain size analysis is a typical laboratory test conducted in the soil mechanics field. The purpose of the analysis is to derive the particle size distribution of soils. A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.
Standard References:-
ASTM D 422-standard test method for particle-size analysis of soils.
Purpose of this experiment
This test is performed to determine the percentage of different grain sizes contained within a soil. The mechanical or sieve analysis performed to determine the distribution of the coarser, larger-sized particles, and the hydrometer method is used the distribution of the finer particles.
Procedure:
First of all we found weight of each sieve as well as the bottom pan and we wrote it to use it in the analysis.
And we found the weight of the given dry soil sample and recorded it.
Then we checked all the sieves to make sure that all of sieves are clean, and assembled them in the ascending order of sieve numbers (#4 sieve at top and #200 sieve at bottom). And we placed the pan below #200 sieve. Carefully we poured the soil sample into the top sieve and place the cap over it.
After that we placed the sieve stack in the mechanical shaker and shack it for 10 minutes.
Finally we removed the stack from the shaker and carefully weighted and recorded the weight of each sieve with its retained soil. Weighted and recorded the weight of the bottom pan with its retained fine soil.
Discussion:
In this test we learn how to find grain size of the soil and how to classify it with comparing to ASTMD standards.
By using gradation curve and our table since F200 (1.55%) <50%, this mean our soil type should be Gravel or Sand.
R4 (22.2%)<12 R200(98.45%)=49.25 and this should be sand.
F200 (1.55%) <%5 so this should be SW or SP.
Our Cu>=6 but our Cg is not between 1 and 3 so our soil is SP.
%gravel (22.2%)>=15%so our soil is SP with gravel.
Conclusion:
In this test we are learn how to fined particle size distribution and classified our soil sample with ASTM D standard which we notice that our soil is poorly grained sand with gravel due to our comparing with ASTMD standard and we drew a particle-size distribution for our sample which is our curve well graded because it take a lot of particle sizes of our soil sample. This test we didn’t have many of sieve numbers this result to this 4.3
Setting Time of Hydraulic Cement By Vicat Needle | Jameel AcademyJameel Academy
This report details an experiment to determine the initial and final setting times of a hydraulic cement using the Vicat needle test method. The cement paste was prepared and tested according to ASTM standards. The initial setting time was found to be 2 hours and 45 minutes when the needle penetration was 6 mm. The final setting time was then calculated using an empirical equation to be 4 hours and 48 minutes. While only two penetration measurements were taken, the results indicate the cement would be suitable for construction uses and meet the Iraqi standard of a minimum 1 hour initial setting time.
Discharge Over a broad Crested Weir | Jameel AcademyJameel Academy
1) The document describes an experiment to measure discharge over a broad crested weir. Water was passed through an inlet tank and discharge tank containing a broad crested weir, and the height and volume of water were measured over time.
2) Using the measured heights and volumes, the actual discharge was calculated and compared to the theoretical discharge calculated using a formula. The ratio of actual to theoretical discharge, known as the coefficient of discharge (Cd), was also determined.
3) The results showed that the Cd increased with increasing water height, and a logarithmic equation was developed to relate Cd to water height. The purpose was to determine discharge over a weir and compare to theory.
1. Sieve analysis was performed on a sample of calcium carbonate to determine its particle size distribution. The sample was shaken in a mechanical shaker through a series of sieves with decreasing mesh sizes for different time intervals.
2. The mass of the sample retained on each sieve was measured and the cumulative percentage passing and particle size distribution curves were plotted.
3. The results showed that increasing the shaking time decreased the particle size, following a bell-shaped curve distribution rather than a direct proportional relationship between particle size and mass fraction.
1. The document provides examples of calculating consolidation parameters such as void ratio, coefficient of consolidation, and primary consolidation settlement from given soil testing data.
2. Parameters like initial void ratio, applied pressure, and thickness of soil layers are used to determine the change in stress and void ratio to then calculate settlement.
3. Several methods are presented to calculate the average effective stress and stress change at different points to then determine the consolidation settlement under different boundary conditions, stress histories, and soil properties.
Specific Gravity & Absorption of Aggregate (Coarse & Fine) | Jameel AcademyJameel Academy
This document reports on a test to determine the specific gravity and absorption of fine and coarse aggregates. The specific gravities of coarse aggregate were found to be 2.55, 2.7, and 2.8 for bulk dry, SSD, and apparent respectively. For fine aggregate, the specific gravities were 2.64, 2.7, and 2.8. The absorptions were 2.3% for coarse and 1.78% for fine. While the specific gravities were normal, the absorptions were outside standard ranges, likely due to errors in measuring the fine aggregate's slump or not waiting 24 hours for coarse aggregate heating. In conclusion, the aggregates tested would not be suitable for use due to
The document describes a standard compaction test performed on a soil sample to determine the maximum dry density and optimum moisture content. Five soil samples with varying moisture contents were compacted and tested. The maximum dry density was found to be 19.1 kN/m3 at an optimum moisture content of 12.2%. A graph of the dry unit weight versus moisture content showed a compaction curve with the highest point indicating the maximum dry density and optimum moisture content. The purpose of the test is to evaluate the engineering properties of soils for use in construction projects.

This document describes procedures for three tests to assess the resistance of aggregates to mechanical degradation: the aggregate impact test, ten percent fines test, and aggregate crushing test. The tests involve placing aggregates in standardized molds and applying controlled impacts or loads to measure the amount of fines produced. The results indicate an aggregate's strength and suitability for uses like road bases that subject it to repeated mechanical stresses. Proper testing helps ensure aggregates meet specifications for withstanding wear in paving and quarrying equipment.

This document describes procedures for determining the Los Angeles abrasion value of aggregates. The test involves placing aggregate samples and steel balls into a rotating steel cylinder. The rotation causes the balls to abrade the aggregate particles. The percentage weight loss of the aggregates after a specified number of rotations is the Los Angeles abrasion value, which indicates the resistance of the aggregates to wear. The test is important because aggregates used in road surfaces need to withstand abrasion from vehicle traffic. The document provides details on the required apparatus, test samples, and step-by-step procedure.

%gravel (22.2%)>=15%so our soil is SP with gravel.
Conclusion:
In this test we are learn how to fined particle size distribution and classified our soil sample with ASTM D standard which we notice that our soil is poorly grained sand with gravel due to our comparing with ASTMD standard and we drew a particle-size distribution for our sample which is our curve well graded because it take a lot of particle sizes of our soil sample. This test we didn’t have many of sieve numbers this result to this 4.3
Setting Time of Hydraulic Cement By Vicat Needle | Jameel AcademyJameel Academy
This report details an experiment to determine the initial and final setting times of a hydraulic cement using the Vicat needle test method. The cement paste was prepared and tested according to ASTM standards. The initial setting time was found to be 2 hours and 45 minutes when the needle penetration was 6 mm. The final setting time was then calculated using an empirical equation to be 4 hours and 48 minutes. While only two penetration measurements were taken, the results indicate the cement would be suitable for construction uses and meet the Iraqi standard of a minimum 1 hour initial setting time.
Discharge Over a broad Crested Weir | Jameel AcademyJameel Academy
1) The document describes an experiment to measure discharge over a broad crested weir. Water was passed through an inlet tank and discharge tank containing a broad crested weir, and the height and volume of water were measured over time.
2) Using the measured heights and volumes, the actual discharge was calculated and compared to the theoretical discharge calculated using a formula. The ratio of actual to theoretical discharge, known as the coefficient of discharge (Cd), was also determined.
3) The results showed that the Cd increased with increasing water height, and a logarithmic equation was developed to relate Cd to water height. The purpose was to determine discharge over a weir and compare to theory.
1. Sieve analysis was performed on a sample of calcium carbonate to determine its particle size distribution. The sample was shaken in a mechanical shaker through a series of sieves with decreasing mesh sizes for different time intervals.
2. The mass of the sample retained on each sieve was measured and the cumulative percentage passing and particle size distribution curves were plotted.
3. The results showed that increasing the shaking time decreased the particle size, following a bell-shaped curve distribution rather than a direct proportional relationship between particle size and mass fraction.

Specific Gravity & Absorption of Aggregate (Coarse & Fine) | Jameel AcademyJameel Academy
This document reports on a test to determine the specific gravity and absorption of fine and coarse aggregates. The specific gravities of coarse aggregate were found to be 2.55, 2.7, and 2.8 for bulk dry, SSD, and apparent respectively. For fine aggregate, the specific gravities were 2.64, 2.7, and 2.8. The absorptions were 2.3% for coarse and 1.78% for fine. While the specific gravities were normal, the absorptions were outside standard ranges, likely due to errors in measuring the fine aggregate's slump or not waiting 24 hours for coarse aggregate heating. In conclusion, the aggregates tested would not be suitable for use due to
The document describes a standard compaction test performed on a soil sample to determine the maximum dry density and optimum moisture content. Five soil samples with varying moisture contents were compacted and tested. The maximum dry density was found to be 19.1 kN/m3 at an optimum moisture content of 12.2%. A graph of the dry unit weight versus moisture content showed a compaction curve with the highest point indicating the maximum dry density and optimum moisture content. The purpose of the test is to evaluate the engineering properties of soils for use in construction projects.

Sieve Analysis for Coarse Aggregate as per ASTM. Slides contain all the relevant data and steps that would be required for the performance of sieve analysis of coarse aggregates.
This document describes procedures for three tests to assess the resistance of aggregates to mechanical degradation: the aggregate impact test, ten percent fines test, and aggregate crushing test. The tests involve placing aggregates in standardized molds and applying controlled impacts or loads to measure the amount of fines produced. The results indicate an aggregate's strength and suitability for uses like road bases that subject it to repeated mechanical stresses. Proper testing helps ensure aggregates meet specifications for withstanding wear in paving and quarrying equipment.
This document describes procedures for sieve analysis of aggregates. Sieve analysis involves passing aggregate samples through a series of sieves to determine the distribution of particle sizes. The key steps are:
1. Obtaining a representative sample and reducing it to the appropriate test size.
2. Separating the sample using sieves into coarse (>10 sieve) and fine (<10 sieve) fractions.
3. Weighing the material retained on each sieve to determine the particle size distribution, expressed as a percentage passing each sieve size.
Calibration of mechanical shakers used in the analysis is also described to ensure an adequate sieving time that retains less than 0.5% of material on any sieve during subsequent hand
This document describes procedures for determining the Los Angeles abrasion value of aggregates. The test involves placing aggregate samples and steel balls into a rotating steel cylinder. The rotation causes the balls to abrade the aggregate particles. The percentage weight loss of the aggregates after a specified number of rotations is the Los Angeles abrasion value, which indicates the resistance of the aggregates to wear. The test is important because aggregates used in road surfaces need to withstand abrasion from vehicle traffic. The document provides details on the required apparatus, test samples, and step-by-step procedure.
Sieving or screen analysis is a common technique used to separate particles by size. It involves shaking a sample through a series of sieves with decreasing mesh sizes to separate particles. This document describes conducting a sieve analysis experiment on calcium carbonate over different time intervals. The results show that longer sieving times of 6 minutes produced the best separation of particles into different size fractions compared to 2 and 4 minute intervals. Sieve analysis provides useful information about particle size distribution that is important for understanding properties and performance.
Combing is a very important process for a spinning mill. The object of combing is removal of short fibres, Neps, impurities and to improve the fibre length uniformity followed with improvement in mean length. The removal of immature cotton, foreign matter and improvement in fibre fineness and fibre bundle strength are the additional advantages of combing process. In totality combing process significantly improves the cotton characteristics by removing the useless fibres (i.e. Fibres which are not suitable for a particular end use) from the process. These fibres are extracted as comber Noil waste. This Complete combing process carried out by action of different combing elements. During combing process along with useless fibres good quality fibres are also removed especially in modern high speed combers which are huge raw material & financial losses for the industry. We have studied in detail the combing action of these different combing elements w.r.t. removal of Neps, SFC % & other impurities with mean length improvement. The object of this article is to present the effect of different combing elements on cotton processed and how we can perfectly set these combing elements to get the better combing process with respect to desire Quality, so we can achieve maximum removal of useless fibres with minimum losses of good fibres.

Introduction
Aggregate gradient (sieve analysis) is distribution of a particle sizes expressed as a percentage of the total dry weight. Gradating ids determined by passing the material thought a series of sieves stacked with progressively smaller opening from top to bottom and weighting the material retained on each sieves.

Purpose of this experiment Determination of the particle size disruption of fine and coarse aggregate by sieving. Determine maximum size of the aggregate.
Procedure First of all we took a sample of the air dry coarse aggregate Then with quartering method we took two piece of our coarse aggregate and we combined it, which its weight equal to 2kilo. After that we arranged our sieves which from the top we put 50mm and in the bottom 4.75mm, and we put a pan at the bottom of our sieves, after that we put our sample at the upper sieve and we covered it and started sieving for 10 min with mechanical sieve shaker. After that we opened the sieves and weighted the residue in each sieve and pan. We found the total sum of all residues and compared it with the original sample weight which there’s no loss of its weights. We calculated the percentage retained in each sieve, cumulative percentage retaining and percentage passing.
Discussion
It is evident that sieves can be used to both fine and coarse aggregate into different particle sizes. The number sieves describes what size of aggregate fall through to the next. In this test we got proper weight of our sample. Due to our graph we note that the aggregate sizes which pass through sieve 9.5 not proper to use because due to ASTM the graph of our sample not being between both of standard graphs. As for example the %pass particle in sieve 9.5 is equal to %0.15 .which due to ASTM this mustn’t being lower than %10 this mean this particles must being smaller to being more than %10 but we can grade it to being more smaller and pass through this sieve as more than %10. But the particular sizes which pass through sieve 4.75, 19, 25 and 50 proper to use because due to our code it stand between both of standard graphs. For that samples which not pass in this test we must add gravel to it or we can grad it to smaller particles.
Conclusion:
We conclude that the sieve analyses are the simple and easy way to determine that particle size distribution on aggregate.

This document describes the sieve analysis test of sand. The test involves sieving various sizes of sand particles through a series of sieves and calculating the percentage of sand retained on each sieve. This determines the particle size distribution. Well graded sand has a wide range of particle sizes, uniformly graded sand has similar sized particles, and gap graded sand is missing some sizes. The test procedure, equipment used, and results/conclusions are explained.
Aggregates are non-metallic minerals that are used in civil engineering constructions like concrete. They can be natural like sand and gravel, or artificial like crushed brick. Aggregates are classified based on size as coarse or fine aggregates. A sieve analysis is done to determine the particle size distribution or gradation of aggregates. A well-graded aggregate mixture has a continuous distribution of particle sizes and leads to stronger concrete. The document discusses different properties of aggregates like gradation, water absorption, specific gravity, and provides examples of sieve analysis and blending aggregates to achieve a target gradation.

Sanjeeb Kumar Satapathy conducted a project to determine the Bond work index of a low-grade iron ore sample. He took a 500kg sample of iron ore and crushed 25kg to below 6 mesh size. He then performed dry size analysis on the crushed sample and determined that 80% passed a 150 micron sieve. He ground 700cc of the crushed sample in a ball mill and performed screening and analysis to determine that 80% of the product passed a 102 micron sieve. Using Bond's equations, he calculated the average net grams produced per revolution of the mill grinding and determined the Bond work index of the iron ore sample was 3.36 kWh/tonne.
Detailed working of each equipments, formulas and calculations. Easy to understand. Very helpful for those students who face difficulty in making lab reports
The document discusses mechanical analysis of soil, which involves determining the particle size distribution of soil through sieve analysis and hydrometer analysis. Sieve analysis involves shaking a dry soil sample through a nested set of sieves to separate particles by size. Hydrometer analysis uses the principles of sedimentation and Stokes' law to determine the percentage of fine particles less than 0.075 mm in diameter. The particle size distribution is presented as a curve showing the percentage of soil finer than each particle size on a logarithmic scale, from which key parameters like effective size, uniformity coefficient, and coefficient of gradation can be calculated. These parameters provide important information about the soil type and properties.

Fineness of fine aggregates perfect (1)Dave Madhav
This document outlines a procedure to determine the particle size distribution of fine aggregates through sieving. The test aims to classify fine aggregates according to grading zones based on percentages retained on various sieve sizes. Fine aggregates are sieved through a series of sieves ranging from 4.75mm to 75μm. The weights retained on each sieve are recorded to calculate the cumulative percentage retained and fineness modulus. The results of this test can be used to inform concrete mix design based on the gradation characteristics of the fine aggregates.

Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications

Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

I. Introduction:
Aggregates are inert materials which are mixed with binding materials such as
cement or lime for manufacturing of mortar or concrete. Aggregates are used as filler in
mortar and concrete. Aggregate size vary from several inches to the size of the smallest grain
of sand. The aggregates (fine + coarse) generally occupy 60% to 75% of the concrete volume
or 70% to 85% by mass and strongly influence the concrete’s freshly mixed and hardened
properties, mixture proportions, and economy. All aggregates pass IS: 4.75mm sieve is
classified as fine aggregate.
All aggregate technicians use the sieve analysis (gradation test) to determines the
gradation (the particle size distribution, by size, within a given sample) in order to determine
compliance with design, production control requirements, and verification specifications.
Used in conjunction with other test, the sieve analysis is a very good quality control and
quality acceptance tool.
Gradation meaning the distribution of particle sizes within the total range of size. It
can be identified on a graph as well graded, uniform, or gap graded (sometimes called skip
graded:
Well graded means sizes within the entire range are in approximately equal amounts,
although there will be very small amount of the largest and smallest particles.
Uniform gradation means that a large percentage of the particles are of the same size.
Gap graded or skip graded means that most particles are of a large size or a small size
with very few particles of an intermediate size.

II. Sample Proportions:
Our desire sample is 1000 grams and to get the Sample, we use the Quartering Method.
Because our sample is dried already, all of us has skipped the drying stage.
- First, we took 4000 grams of Fine aggregates from the bag and start the quartering method.
- Secondly, we distributed a shovel full of fine aggregate as uniformly as possible over a wide
at pile that is reasonably uniform in thickness and diameter.
- Then, we divided the pile cleanly into equal quarters with a square-ended shovel. Next, we
distributed the rest into halves, then into quarters.

V. Result & Discussion:
As we can see from both graphs above, the quartering method worked really well for us
since there is not much difference in both graphs, and after the discussion, our group agreed
that the aggregates that we took the sample from is not the ideal aggregate to use in concrete
mixing because its particle distribution is not even enough to compact each other.
To sum up, Sieve analysis of fine and coarse aggregates are really important and needed
before buying the aggregates for every construction and we must follow each steps very
carefully in order to obtain a very clear and precise result.
