Abstract:In the process of life-cycle of concrete,sulfate attack and freeze-thaw cycles are two important factors that affect the durability of concrete structures.The damage process of pumping concrete with water to cement ratio of 0.44 under immersion-dry cycles or immersion-dry-freeze-thaw cycles in solutions of 6.0% Na2SO4 is studied.The results show that the relative dynamic modulus of elasticity Erd increases linearly and the damage variable Dm(T)=0 in the initial stage of immersion-dry cycles,but according to the immersion-dry cycles increased,the damage variable D experienced the process from 0 to slow increasing,at last rapid increasing,and the relative dynamic modulus of elasticity Erd experienced the process from increasing linearly to decreasing slowly.Compared with the immersion-dry cycles,the interactive effects of immersion-dry cycles and freeze-thaw cycles have greatly accelerated the process of concrete damage.
