Evaluation of physical properties of clays mixed with silica sand

This study examined the effects of heat treatment on two types of clays mixed with silica sand under laboratory conditions. Soils were subjected to three varied temperatures, i.e. 100, 250 and 500°C. The soil properties studied were Atterberg’s limits, optimum water content and unconfi ned compres...
