Abstract

Avoiding of unsuitable site conditions is not practically possible due to rapid urbanization, so there is a need for soil stabilization. Now-a-days environment is getting polluted by disposal of waste into water bodies without adequate treatment due to which chemical behaviour of water may vary which causes changes in pH of water. This study deals with stabilization of expansive soils using ordinary Portland cement and Portland slag cement separately with different proportions (3%, 5%, 7.5% and 10%) under varying pH conditions (pH=5, pH=7, and pH=9) using UCS and CBR tests. The main objective of this study was to find out the effect of acidic and alkaline nature of curing water on strength characteristics of two different stabilized soils with respect to curing periods (7,14, and 28 days). The test results clearly have shown a significant improvement in strength characteristics of stabilized soils with respect to curing ages.
