Experimental study on behavior of mortar-aggregate interface after elevated temperatures

Wan WANG, Jianzhuang XIAO, Shiying XU, Chunhui WANG

Frontiers of Structural and Civil Engineering 2017, Volume 11, Issue 2,   Pages 158-168 doi: 10.1007/s11709-016-0374-6

Abstract: after elevated temperatures ranging from 20°C to 600°C with the concept of modeled concrete (MC) andmodeled recycled aggregate concrete (MRAC).For MRAC, the cracks appeared at a lower level of load with the increasing elevated temperatures.For MC and MRAC with higher strength of new hardened mortar, the residual peak load kept constant whenFor MRAC with lower strength of new hardened mortar, the residual peak load began to reduce when the
