Abstract

Abstract

Seawater-coral aggregate concrete has become a new type of building material for constructions in islands and reefs,supporting the development of ocean exploration in China. Based on the stage divisions of whole life cycle of seawater-coral aggregate concrete structures,the influences of salinity in seawater on early-age hydration of cement were summarized. A concept of two-level transmission routes through coral aggregate and cement matrix respectively was proposed. The main mechanism of mineral corrosion and the damage and destruction process under mitigation were reviewed. Main gaps and suggested key issues were expected to be valuable for future researches on the durability problem of seawater-coral aggregate concrete.
