Experimental study and assessment of thermal energy storage mortar with paraffin/recycled brick powder composite phase change materials
文献摘要：
Thermal energy storage recycled powder mortar(TESRM)was developed in this study by incorporating paraffin/recycled brick powder(paraffin/BP)composite phase change materials(PCM).Fourier transform infrared and thermogravimetric analysis results showed that paraffin/BP composite PCM had good chemical and thermal stability.The onset melting temperature and latent heat of the composite PCM were 46.49℃and 30.1 J-g-1.The fresh mortar properties and hardened properties were also investigated in this study.Paraffin/BP composite PCM with replacement ratio of 0％,10％,20％,and 30％by weight of cement were studied.The results showed that the static and dynamic yield stresses of TESRM were 699.4％and 172.9％higher than those of normal mortar,respectively.The addition of paraffin/BP composite PCM had a positive impact on the mechanical properties of mortar at later ages,and could also reduce the dry shrinkage of mortar.The dry shrinkage of TESRM had a maximum reduction about 26.15％at 120 d.The thermal properties of TESRM were better than those of normal mortar.The thermal conductivity of TESRM was 36.3％less than that of normal mortar and the heating test results showed that TESRM had good thermal energy storage performance.
