Abstract
This paper discusses the use and efficacy of rice husk ash (RHA) as a stabilizing additive to problematic expansive soils. RHA is an agricultural industrial waste. It is abundantly available and therefore needs to be effectively disposed. The paper presents experimental results obtained from tests conducted on RHA-clay blends. Liquid limit, plasticity index, free swell index (FSI), compaction characteristics, strength parameters, and CBR were determined on the expansive clay specimen to which RHA was added in different quantities such as 5, 10, 15, 20… 50% by dry weight of the soil. Test results indicated that FSI and PI decreased with increasing RHA content. Further, CBR and angle of internal friction increase while cohesion decrease.
