Mechanical and Thermal Behaviors of Cement Stabilized Compressed Earth Bricks

Abstract

Cement stabilized compressed earth brick is an important industrial raw material, and its mechanical and thermal properties have not been fully studied. The mechanical properties can be characterized by compressive strength index and thermal properties can be characterized by thermal conductivity index. The experimental scheme is arranged to solve the relationship between the performance of cement stabilized compressed earth brick and the influencing factors. The experimental results show that the compressive properties of cement stabilized compressed earth bricks are negatively correlated with the water binder ratio, positively correlated with the m (cement): m (water), and not significantly correlated with the m (earth): m (cement + water) and the fiber content. The thermal conductivity of raw soil cement curing mechanism brick is negatively correlated with m (earth): m (cement + water), positively correlated with water binder ratio, and not significantly correlated with m(cement): m (water) and fiber content.
