Experimental study on thermodynamic characteristics of EPS lightweight soil

Abstract

The dynamic triaxial tests of EPS light soil were carried out under the conditions of different temperature, dynamic stress, EPS mixing ratio, cement content and age period, and the effect of temperature on the dynamic properties of EPS light soil is analyzed prominently. The results show that with the increase of temperature, the dynamic elastic modulus of EPS light soil increases and the soil appears the phenomenon of thermal hardening. With the increase of cement content, the thermal hardening effect of the sample decreases, and the effect of cement content is greater than that of EPS content.
