Effect of Rice Husk Ash on the Shear Strength Parameters of Silty Sand

Anurag Gangwar | Anoopsingh Chandel

Abstract: It is a known truth that sand possesses zero cohesion. As a consequence, the resulting shear strength parameters are of poor nature. If sand is to be used for the purpose of embankments such as in desert areas of Thar and Katchh, it is inevitable that the shear strength parameters of a sandy soil should be improvised. The present study aims at improving the shear strength parameters of chosen soil sample i. e. silty sand with the help of a natural waste (rice husk ash). Shear strength parameters are evaluated using direct shear test. Also with the addition of varying proportions of rice husk ash (RHA), CBR test are carried as a check parameter. The detailed study and discussions can be described as below.

Keywords: Silty sand, Rice husk ash RHA, Particle size distribution, shear strength parameters, Cohesion c, angle of internal friction, Direct shear test, CBR test
