Some experimental results of research on the time variation law of coral concrete strength

Abstract

The article presents research results on the time variation law of coral concrete strength at durability levels B15, B20, and B22.5 (using aggregates of sand, coral stone, and seawater). The results show that the relationship between seawater coral concrete's strength and time is a logarithmic function (within 360 days of testing). Depending on the level of durability, the dependence of concrete strength over time with different representation functions is logarithmic. This shows that seawater coral concrete of normal durability level, prepared according to the same principle as conventional concrete (using traditional aggregates and water), will have the same structure and strength development as conventional concrete.
