The document provides information on concrete foundations, including the key ingredients of concrete and their functions. It discusses different grades of concrete based on their compressive strength. Formwork, mixing, placing, compaction and curing of concrete are explained. Different types of foundations are described, including shallow foundations like spread footings, strap footings and mat foundations. Deep foundations such as pile foundations and pier foundations are also summarized. Load bearing and framed structures are compared in terms of their suitability for different types of buildings and soils.
The document discusses different types and uses of concrete. It describes three ways concrete can be classified: by binding material (cement or lime concrete), design (plain, reinforced, or pre-stressed concrete), and purpose (vacuum, air entrained, or light weight concrete). For each type, the key ingredients and common uses are provided. The document also covers mix design ratios, water-cement ratios, slump and workability tests, and the compaction factor test for evaluating concrete workability.
The document discusses reinforced cement concrete (RCC), including its history, materials, specifications, and advantages/disadvantages. RCC uses steel reinforcement embedded in concrete to resist tensile, shear, and sometimes compressive stresses. François Coignet is considered a pioneer of RCC, building the first reinforced concrete structure in 1853. Proper proportions and mixing of cement, aggregates like sand and gravel, and water are needed to produce durable concrete. Precast concrete involves casting pieces off-site then transporting them for assembly.
This document provides an overview of concrete, including its composition, properties, production process, and testing. Some key points:
- Concrete is a composite material made of cement, fine and coarse aggregates, and water. It can be classified based on its cementing material, mix proportions, performance specifications, grade, density, and place of casting.
- The production of concrete involves batching, mixing, transporting, placing, compacting, curing, and finishing. Proper batching and mixing are important to ensure uniform strength. Compaction removes entrapped air for maximum strength. Curing maintains moisture for proper hardening.
- Concrete properties depend on water-cement ratio, with maximum theoretical
Formwork is a temporary mold used to contain poured concrete until it cures and can support itself. It needs to be strong enough to support the weight of wet concrete and withstand pouring and compaction loads. New materials like steel and plastics are now used for formwork in addition to wood. Slipforming allows for continuous vertical pouring of concrete structures like building cores without relying on external support, by using a formwork that rises slowly on its own as concrete is added.

Self-compacting concrete (SCC) is a highly flowable concrete that can spread into place and fill formwork without any mechanical consolidation. SCC was developed in Japan in the 1980s to overcome issues with inadequate consolidation of traditional vibrated concrete. SCC uses special admixtures and optimized aggregate gradation to achieve excellent flowability, passing ability, and segregation resistance. While SCC has higher material costs, it provides benefits of easier placement, improved quality, reduced labor requirements, and faster construction.
Soil nailing is a technique used to reinforce and strengthen existing ground.Soil nailing consists of installing closely spaced bars into a slope or excavation as construction proceeds from top down.It is an effective and economical method of constructing retaining wall for excavation support, support of hill cuts, bridge abutments and high ways.This process is effective in cohesive soil, broken rock, shale or fixed face conditions.
Construction materials testing (CMT) involves testing materials used in construction projects to ensure quality. The specific tests conducted depend on the materials and project scope, but often include tests of aggregates, cement, concrete, steel reinforcement, and other common construction materials. Standard test methods have been established by organizations like ASTM and ISO. Test results help ensure construction materials meet design specifications and standards.
Cement concrete is a composite material consisting of a binding material (cement or lime), aggregates (fine and coarse), water, and admixtures. The cement and water form a paste that coats the aggregates and binds them together. Concrete can be classified based on its constituents, method of production, place of casting, and bulk density. Proper curing is important for concrete to gain strength and hardness through hydration. Common curing methods include water curing, membrane curing, and steam curing. The water-cement ratio significantly impacts concrete strength, with lower ratios producing stronger concrete.
This document summarizes the construction of rigid pavements. Rigid pavements use plain cement concrete slabs with dowel bars at joints for load transfer. They are used in areas with adverse conditions like heavy rainfall, poor soil/drainage, or extreme climate. Materials include cement, coarse and fine aggregates, and water. Construction involves subgrade preparation, forming slabs with joints, curing, and allowing time before opening to traffic. Joints include longitudinal, contraction, and expansion joints with filler and dowel bars to allow for expansion/contraction. Reinforcement improves strength and load distribution. Advantages include durability and low maintenance, while disadvantages include higher initial costs and traffic disruption during repairs.
Concrete is an important construction material due to its strength, durability, versatility and cost-effectiveness. It is composed of cement, water and aggregates. Concrete offers advantages such as durability under various weather conditions, the ability to be molded into different shapes, fire resistance, sustainability and ease of construction. These properties make concrete widely used for infrastructure, housing and commercial structures.

Lightweight concrete uses lightweight aggregates to reduce density compared to normal concrete. It is used to reduce structural loads and transport/handling costs. High density concrete uses heavy aggregates like iron or lead to increase density above 2600 kg/m3. It is used for radiation shielding, counterweights, and seawalls. Shotcrete is concrete sprayed at high velocity through a hose. It is used for tunnel linings and slopes due to its ability to coat any surface. Fibers are added to concrete to increase crack resistance and tensile strength. Different fiber types include steel, glass, and polymers.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
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.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdfBalvir Singh
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days

6. Site plan and planning
• The planning of the building has the most important role in the civil
engineering because well designed building has the comfort and good
working conditions for the people who live and work in it .
• The project on which I take training it is a construction of residential
buildings. This building is designed very carefully by keeping the
following views:
• Swimming pool.
• Aerobics and yoga room.
• Media rooms for watching movies etc. 40-50 seats.
• Sports lounge.
• Community Hall.
• Library.
• Kids play area ,Car Parking..
7. Building Material
• A building structure is composed of different types of the material these
materials are either called as building material. The material use in the
building on basis of the availability and cost. For construct a building the
essential.
• building material are as follows
8. • Cement: The cement often called the magic power is a fine ground
material consisting of compound of lime ,silica alumina and iron. When
mixed with water it forms a paste which hardened and bind the aggregates
(sand, gravel ,crushed rock, etc.) together to form a durable mass called the
Concrete.
• Sand :These are cohesion less aggregates of either, rounded sub rounded,
angular, sub angular or flat fragments of more or less unaltered rock of
minerals consisting of 90% of particles of size greater than 0.06 mm and
less than 2 mm.
• Bricks : Bricks are distinguished by their base (row) material and size.
Standard brunt clay bricks come in the size 10" x 5" x 3". Modular bricks,
rarely used because they are not easily available, come in the size 200mm x
100mm x 100mm (including mortar thickness) Fly ash bricks, sometimes
also come in modular form.
9. EXCAVATION
• Excavation- Foundation trenches shall be dug out to the exact
width of the foundation concrete and the sides shall be vertical.
If the soil is not good and does not permit vertical sides, the
sides should be sloped back or protected with timber shoring.
•
• Finish and Trench- The bottom of the foundation trenches
shall be perfectly leveled both longitudinally and transversally
and the sides of the trench shall be dressed perfectly vertical
from bottom up to least thickness of lose concrete may be laid
to the exact width as per design. The bed of the trench shall be
tightly watered and well rammed. Soft or defective spots shall
be dug out excess digging if done through mistake shall be
filled with concrete
10.
11. FOUNDATION
• The foundation of the building should
be so planned and the layout of the
foundation should be on the ground
should be correct in the measurement.
• Should not place the concrete in the
foundation before checked by the
Engineer-in charge.
• If building has the basement more than
two raft foundations should be provided.
• In the P.C.C. it should be in the ratio of
1:4:8 and 75 mm thick 75 mm projected
beyond raft foundation.
• The concrete provided in the raft
foundation should be M-25 grade
conforming to IS456.
• The design and thickness of the raft
foundation provided by the soil testing
12. Retaining Wall
• A retaining wall is a structure designed and constructed to resist the lateral
pressure of soil when there is a desired change in ground elevation that
exceeds the angle of repose of the soil.
• A basement wall is thus one kind of retaining wall. But the term usually
refers to a cantilever retaining wall, which is a freestanding structure
without lateral support at its top. These are cantilevered from a footing and
rise above the grade on one side to retain a higher level grade on the
opposite side. The walls must resist the lateral pressures generated by loose
soils or, in some cases, water pressures.
13. Manufacturing of concrete
• Batching of the concrete
• After fixing the proportion of different ingredients of concrete for a
particular work, the material C.A., F.A., cement and water measured out in
batches for mixing. The process is known as Batching. This process of
batching may be carried out by weight or by volume.
• (i) Weight batching: - The unit of weight, for material of concrete, is
usually Kilogram. The batching of material by weight is absolutely straight
forward, the cement, sand and coarse aggregate being all weighed directly
in Kilogram.
• (ii) Volume batching: -In batching by volume, all ingredient i.e. water,
cement, sand and coarse aggregate are measured in liters, where the
resulting concrete(being) solid measured in cubic meters.
14. Curing of concrete
• Curing is one of the most important steps in concrete construction, because
proper curing greatly increase concrete strength and durability. Concrete
hardened as a result of hydration: the chemical reaction between cement
and water. However, hydration occurs only if water is available and if the
concrete temperature stays within a suitable range. During the curing
period from five to seven days after placement for conventional concrete
the concrete surface needs to be kept moist to permit the hydration process.
New concrete can be wet with soaking hoses, sprinklers or covered with
wet burlap, or can be coated with commercially available curing
compounds, which seal in moisture.
• Curing the concrete aids the chemical reaction called hydration. Most
freshly mixed concrete contains considerably more water than is required
for complete hydration of the cement; however, any appreciable loss of
water by evaporation or by otherwise will delay or prevent the hydration.
15. Plastering
• The joints of the brick work shall raked out to a depth of 12 mm and the surface of
the wall washed and clean and kept wet for the two days before plastering. The
material of mortar should be of standard specification.
• The thickness of the plastering shall be of 12mm to ensure uniform thickness of
plaster; patches of 15 cm shall be applied first at about 2 m apart to act as guide.
• Wall plastering shall be started from top and worked down towards floor,. Ceiling
plastering shall be completed before starting of wall plaster.
• All corner and edge shall be rounded. The plastered surface shall be kept wet for
10days the surface should be protected from rain, sun, frost, etc.
• For wall plastering 1:5 cement mortar and for ceiling plastering 1:3 cement mortar
with coarse sand is used.
16. Formwork
• ‘Temporary Supporting
Structure’are those structures,
which are temporarily required in
building construction, either for
supporting the laying of concrete
till it gets matured, such as?
• formwork or forms or
shuttering. As fresh concrete is in
a plastic state, when it is placed
for construction purposes, so it
becomes necessary to provide
some temporary structure to
confine and support the concrete,
till it gains sufficient strength for
self supporting. The temporary
structure is known as formwork or
shuttering
17. Slump Test
• Dampen inside of cone and place it on a smooth, moist, non-absorbent,
level surface large enough to accommodate both the slumped concrete and
the slump cone. Stand or, foot pieces throughout the test procedure to hold
the cone firmly in place.
• Fill cone 1/3 full by volume and rod 25 times with 5/8-inchdiameter x 24-
inch-longhemispherical tip steel tamping rod. (This is a specification
requirement which will produce nonstandard results unless followed
exactly.) Distribute rodding evenly over the entire cross-section of the
sample.
• Fill cone 2/3 full by volume. Rod this layer 25 times with rod penetrating
into, but not through first layer. Distribute rodding evenly over the entire
cross section of the layer.
• Fill cone to overflowing. Rod this layer 25 times with rod penetrating into
but not through, second layer. Distribute rodding evenly over the entire
cross section of this layer.
• Remove the excess concrete from the top of the cone, using tamping rod as
a screed. Clean overflow from base of cone.

19. Cube test
• The compressive strength of the concrete cube test provides an idea
about all the characteristics of concrete. By this single test one judge that
whether Concreting has been done properly or not. Concrete compressive
strength for general construction varies from 15 MPa (2200 psi) to 30 MPa
(4400 psi) and higher in commercial and industrial structures.
• Compressive strength formula for any material is the load applied at the
point of failure to the cross-section area of the face on which load was
applied.
• Compressive Strength = Load / Cross-sectional Area

21. Conclusion
The main aim of studies within this project was to investigate
how a structure is constructed within its desired properties. We
get knowledge about the basic & advanced techniques of
building construction as well as saw the challenges which a
civil engineer have to face during construction i.e. labor
problems, cost management, environmental challenges
etc. We cleared our many doubts regarding building
construction. We had seen dewatering system at project site for
construction which is not used at our state anymore, so it was a
new thing for us...Although are subjects more important for
technicians, in the project .how Project needs a very good
coordination and large quantities of man power, equipment and
funds ..
