Experimental study and assessment of thermal energy storage mortar with paraffin/recycled brick powder

Luchen HAO; Jianzhuang XIAO; Wanzhi CAO; Jingting SUN

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 10,   Pages 1301-1314 doi: 10.1007/s11709-022-0883-4

Abstract: 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).The fresh mortar properties and hardened properties were also investigated in this study.at later ages, and could also reduce the dry shrinkage of mortar.The thermal properties of TESRM were better than those of normal mortar.
