The evolution of the microstructure and mechanical properties of coral aggregate mortar under uniaxial compression using ultrasonic analysis

This study investigated the compression behavior of coral aggregate mortar (CAM) under uniaxial loading using ultrasonic pulse velocity measurements. Silica sand mortar (SSM) was used for comparison. The results indicated that the compressive strength of the CAM was slightly higher than that of the SSM prepared with similar-sized silica sand. Numerous open pores in the porous structure of the coral aggregate provided water reservoirs for...
