Experimental Investigation on Compaction and CBR Characteristics of Soils using Brick Dust and Cement as Stabilizing Agents

Abstract

In the present research work, brick dust and cement were mixed with soil to investigate the relative strength
gain in terms of compaction characteristics and California Bearing Ratio value. The addition of cement and brick
dust was found to improve the engineering properties of soil in stabilized forms specifically strength, workability, and
compaction and California Bearing Ratio characteristics. Laboratory tests such as compaction, Atterberg’s limits, and
California Bearing Ratio were carried out for different percentages of Brick bust, cement and original soil samples.
The laboratory tests were conducted as per Indian Standard specifications. The present experimental investigation
showed that there is decrease in Optimum moisture content, increase in Maximum Dry Density, decrease in liquid and
plastic limit values and also a tremendous increase in the CBR value of the soil treated with brick dust and cement,
thus leading to decreased thickness requirements of the sub-base and base courses.
