摘要
研究高导热复合相变微胶囊等质量取代砂对混凝土性能的影响,并利用保温瓶模拟绝热环境研究其对水泥净浆绝热温升的影响。结果发现:随着相变微胶囊掺量增加,混凝土工作性能及力学性能均不断降低,但控温效果逐渐增强,当其掺量为20 kg/m3时,水泥净浆温峰较纯水泥净浆可降低7.8℃。
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 20 kg/m3,the temperature peak of cement paste can be reduced by 7.8 ℃.
