Abstract
More than 20% of the land area of India is covered by expansive soil. It is found in Madhya Pradesh, Maharashtra, Andhra Pradesh, Gujarat, Tamil Nadu, Karnataka, and other parts of India. Soils with a lot of clay and a lot of space can change their volume in ways that aren't good. When the amount of water in the soil changes, the volume of the soil also changes.
Since many years ago, engineers have had trouble with the amount of water in expansive soil. For geotechnical engineers, this stress shows up as constant worry about the uplift of expansive soil caused by increased or decreased moisture content in foundation soil. For pavement engineers, it shows up as a lot of worry about longitudinal cracks on pavements if the subgrade soil is expansive and has a lot of moisture change throughout the year.
This study shows the results of an experiment on how to improve the geotechnical properties of loose soil by stabilizing it with solid plastic wastes and brick powder. Even materials that don't make the cut are expected to have basic qualities like strength, stiffness, and permeability. If these things aren't true, engineers are supposed to come up with ways to make the ground better. Due to the rising cost of traditional stabilizing agents like lime and cement and the need to use industrial and agricultural wastes in engineering in a cost-effective way, researchers are looking into whether Brick Powder can be used to stabilize highly expansive clay soil. Brick Powder is a byproduct of industry that can be used in building materials if it has the right physical, chemical, and mechanical properties. The goal of this research is to find out how well Brick Powder and solid plastic waste can hold clay soil together.
As part of the lab work, index properties were used to sort the soil samples. Most of the time, the soils in this class are not good enough to build on. Atterberg limits, grain size analysis, specific gravity, free swell test, compaction, and CBR tests will be used to evaluate the geotechnical properties of stabilized soil and compare them to standards.
Brick Powder was added at 5%, 10%, 25%, and 50% of the soil's dry weight to stabilize it. Adding 0.25 %, 0.5 %, 0.75 %, and 1 % plastic waste strips enhanced the soil.
