Vibration method for ground improvement techniqueABHISHEK THAKKAE
This document discusses various ground improvement techniques, including vertical drains, soil nailing, stone columns, vibro compaction, and dynamic compaction. Vertical drains accelerate consolidation by facilitating drainage of pore water through columns of pervious material placed in soil. Soil nailing uses steel tendons drilled and grouted into soil to create a reinforced composite mass. Stone columns form vertical columns of compacted aggregate through problem soils to increase strength and reduce compressibility. Vibro compaction densifies loose sands using vibratory probes to achieve a denser soil structure. Dynamic compaction improves soil by repeatedly dropping heavy weights onto the ground from heights of 40 to 80 feet.

The document summarizes a study on stabilizing black cotton soil using different stabilizers like lime, bagasse ash, and demolished waste concrete. Black cotton soil is problematic for construction due to its high swelling and shrinkage properties. The study aimed to investigate using agricultural and industrial waste to stabilize the soil. Various properties of the untreated black cotton soil and soil mixed with 5% lime and varying percentages (10%, 20%, 30%) of bagasse ash and demolished concrete were tested. The results showed that the liquid limit, plastic limit, and moisture content decreased while the dry density and unconfined compressive strength increased with the addition of stabilizers. Demolished concrete was found to be more effective at improving properties compared to bagasse
Improved Concrete Properties Using Quarry Dust as Replacement for Natural SandIJERD Editor
Concrete plays a major role in the construction industry. Natural sand is a prime material used for
the preparation of concrete and also plays an important role in Mix Design. Now a day’s river erosion and other
environmental issues have led to the scarcity of river sand. The reduction in the sources of natural sand and the
requirement for reduction in the cost of concrete production has resulted in the increased need to find new
alternative materials to replace river sand so that excess river erosion is prevented and high strength concrete is
obtained at lower cost. One such material is Quarry stone dust: a by-product obtained during quarrying process.
Attempts have been made to study the suitability of Quarry dust as sand replacing material and it has been found
that Quarry dust improves the mechanical properties of concrete as well as elastic modulus. The optimum
compressive strength is achieved at the proportion of fine to coarse with 60:40 ratio
Experimental Study on Properties of Black Cotton Soil Mixed Stone Dust and Si...ijtsrd
Experimental Studies were conducted to see the effects on strength behavior of Black cotton soil using stone dust and Sisal fiber. In this study, the stabilizing effect of sisal Fiber Natural Fiber on soil properties. Keeping this in view an experimental study is conducted on locally available i.e. expensive soil mixed with varying percentage of Stone dust and Sisal fiber. Soil samples for California bearing ratio CBR tests are prepared at its maximum dry density MDD corresponding to its optimum moisture content OMC in the CBR mould without and with sisal fiber. Tests result indicates that both unsoaked and soaked CBR value of soil increases with the increase. Soaked CBR value increases from 3.97 to 9.75 and un soaked CBR value increases from 8.1 to 40.7 of soil mixed with stone dust and sisal fiber. Due to sisal fiber reinforcement CBR is increased resulting lesser thickness of pavements are used in construction works. Soil becomes ductile in nature. This is because of composite effect of sisal fibre Natural Fibre changes the brittle behavior of the soil to ductile behavior.

IRJET- Amendment of Geotechnical Properties of Clayey Soil using Brick Kiln D...IRJET Journal
This document summarizes a study on amending the geotechnical properties of clayey soil using brick kiln dust and Alccofine 1101. Laboratory tests were conducted including the Atterberg limits test and compaction test on clayey soil mixed with varying proportions of brick kiln dust from 10-25% and Alccofine 1101 from 3-9%. Previous studies found these admixtures can increase the strength properties of soil and decrease swelling. The results of this study showed that adding these materials decreased the liquid limit and plasticity index of the clayey soil while increasing the maximum dry density and compressing strength.
IMPROVEMENT OF EXPANSIVE SOIL USING LIME & WASTE GLASS POWDERIRJET Journal
The document presents an experimental study on improving the properties of expansive soil through stabilization with waste glass powder and lime. Several laboratory tests were conducted on untreated and treated soil samples, including specific gravity, liquid limit, plastic limit, free swell index, standard proctor, and CBR tests. The aim was to determine the percentage of waste glass powder and lime required to maximize soil strength. Results showed that adding up to 10% waste glass powder and 2% lime increased the specific gravity, reduced the liquid limit and plasticity index, and improved the CBR value compared to untreated soil, with the optimum mix being 6% glass powder. This indicates waste glass powder and lime can effectively stabilize expansive soil.

ENHANCEMENT OF SOIL SUBGRADE PROPERTIES USING TERRASIL AND ZYCOBOND WITH WAST...IRJET Journal
This study evaluated enhancing the strength properties of black cotton soil through treatment with Terrasil, Zycobond, and waste foundry sand. Testing showed that treating soil with 0.1% Terrasil and Zycobond by dry weight of soil and 30% waste foundry sand yielded significant strength gains. The treated soil exhibited increased maximum dry density and CBR, decreased free swell index, and higher unconfined compressive strength compared to untreated soil. The results demonstrate the effectiveness of these additives for improving the engineering properties of problematic black cotton soil.

31. As the Black Cotton soil is stabilized by 5% GGBS and
varying percentage of Granite Dust.
• MDD increases from 1.58g/cc to 1.82g/cc up to the
addition of 30% of Granite dust and @ 40% addition of
Granite dust the MDD decreases to 1.78g/cc.
• The OMC decreased due to the increases in specific
surface area i. e by the addition of Granite dust.
• The MDD @ 40% decreases because of, addition of
water beyond optimum moisture content, it reduces
dry density due to the presence of extra water occupies
the space which the soil could have occupied.
32. CBR value and UCC value increases because the gain
in strength due to the addition of granite dust.
CBR value increases from 2.37% to 10.26%. UCC
value is increased from 37.52KN/m² to 130.17KN/m².
33. As the stabilization of black cotton soil using 5%
Renolith and varying percentage of granite dust.
MDD increases from 1.58g/cc to 1.8g/cc up to the
addition of 40% of Granite Dust.
MDD increases due to the binding effect of Renolith
and OMC decreases due to the increase in specific
surface area.
CBR value and UCC value increases because the gain
in strength due to the binding effect of Renolith.
CBR value increased from 2.37% to 14.71%. UCC
value increased from 37.52KN/m² to 141.81KN/m²
34. From the experimental study we can conclude that:
The compaction characteristics of the black cotton soil
effectively improved with the addition of granite dust.
With the addition of granite dust for Black Cotton Soil the
CBR value is increased to 14.71% for Renolith and 10.26%
for GGBS.
Increase in the strength and stability characteristics.
