Effect of SiC dosage on compressive strength, flexural strength, and bond flexural strength of geopolymer mortar at high temperature

AIP Advances
This paper investigates the influence of SiC dosage on the high-temperature mechanical properties (compressive strength, flexural strength, and bond flexural strength) of geopolymer mortar. The findings reveal that appropriate amount of SiC was found to improve the high-temperature mechanical properties of geopolymer mortar.
