Stabilization Of Clay Soil With Rice Husk Ash And Cement

Abstract

The study examines the efficacy of stabilizing "Black Cotton Soil" (BCS) by the utilization of a blend of "Rice husk ash" (RHA) and cement. BCS, renowned for its significant expansiveness and limited load-bearing capacity, poses difficulties in construction endeavors. The study aims to examine whether the addition of RHA (Rice Husk Ash) and cement can enhance its engineering properties or not. It covers the impact of different "Cement-Rice Husk Ash" amounts on the Geotechnical qualities of consisting of soil with a high clay content that is dark in color. The physical characteristics of RHA, cement, and BCS were determined. The soil stabilization of BCS samples is evaluated through studies by mixing different amounts of RHA and cement and experiments such as compaction, "Unconfined Compressive Strength" (UCS), and California Bearing Ratio (CBR) are undertaken to assess the soil's stability. The test results indicate that the use of Cement-RHA mixtures can effectively maintain BCS for highway construction purposes. This study examines the effects of several combinations of cement (6% and 8%) and RHA (4%, 8%, 12%, 16%, and 20%) on compressive strength, CBR, and economy. The use of cement and RHA can enhance the stability of soil, hence rendering BCS a more viable choice for constructing foundations
