Abstract

EFFICACY OF CBR ON COPPER AND STEEL SLAG IN EXPANSIVE SOILS

Dr. K. Suresh*, P. Suresh Kumar and K. S. V. Praveena

ABSTRACT

A large part of Central India and a portion of South India are covered with black cotton soils. These soils have high swelling and shrinkage characteristics and extremely low CBR value and shear strength. Hence, there is need for improvement of these properties. The present study is aimed at determining the behavior of black cotton soil reinforced with steel slag and copper slag in a random manner. The soil used is a type of black cotton soil collected from Vempalli, Kadapa District, at a depth of 1.5 m from the natural ground level. The soil samples were prepared at four different percentages of steel slag (5, 10, 15 & 20% by weight of soil) and keeping 20% copper slag as constant. CBR test for 4 days soaking period for both treated and untreated soil samples.
