This paper studied the effect of replacing sand with high thermal conductivity composite microencapsulated phase change material on the performance of concrete,and used thermos flask to simulate the adiabatic environment to study its effect on the adiabatic temperature rise of cement paste.The results show that with the increase of the content of phase change material,the workability and mechanical properties of concrete decrease,but the temperature control effect increases gradually.When its content is 20kg/m3,the temperature peak of cement paste can be reduced by 7.8 ℃.
