In order to evaluate the compressive creep behavior of expanded polystyrene (EPS), on the basis of the analysis of actruality research of the EPS compressive creep, the subsection creep curves were gained by applying the stepped isothermal method (SIM) to the investigation of compressive creep. In addition, the temperature effect on the compressive strength was studied. The results showed that the slope of strength versus temperature changed abruptly, and led to a significant increase in the creep rate at 4...
