Soil Stabilization With Rice Husk Ash And Lime Sludge

Abstract

Chemical stabilization of soil using cement, lime, etc. is costly. In order to introduce new material which can reduce the cost of chemical stabilization a review is made on rice husk ash. Rice husk is a waste material from paddy crop. After burning it gives the rich amount of silica which may be used as chemical stabilizer for soil stabilization.the present investigation has been carried out with agricultural waste materials like rice husk ash (RHA) and cheaply available lime is mixed with clayey soil improvement of weak sub grade in terms of compaction and strength characteristics. in this investigation lime and rice husk ash (RHA) is added 5%, 10% 15% and 20% by weight of soil. Various tests were also conducted on these mixes in order to find optimum proportion.  The main objective of this investigation is to access cheaply availability of lime and rice husk ash for improving engineering property of clayey soil for making capable of taking more load form structure to foundation
