Ecological construction materials such as earth concrete containing a proportion of various ecological components are of great importance today. The aim of the production of such a concrete is to reduce the consumption of cement and hence the reduction of CO2 emissions. This work studies the effect of crushed sand on the thermomechanical properties of compressed and stabilized earth concretes, from the point of view of mass loss, compressive strength and thermal conductivity. In this context, four sand contents were used (0%, 20%, 50%, 70%) by weight of the dry mix, with 10% cement to stabilize it. The results indicate that there is an improvement in the thermomechanical properties of (CEC) for a sand rate of 20%.
