Permeability and Compressibility Behavior of Bentonite

Although bentonite sand soil mixes are used widely there is no specific engineering approach to proportion these mixes that satisfies the above practical requirements In this paper a generalized approach is presented for predicting the permeability and compressibility characteristics of mixes with minimum input parameters
