Abstract The development and construction of the South China Sea reefs exaggerate the gravity of local shortage of concrete aggregate sources. Most of the South China Sea islands have the geological structure of coral reefs, and the use of coral aggregate to replace ordinary aggregates for concrete preparation opens a plausible approach to the above mentioned problem. Based on the current worldwide research of coral aggregate concrete, this article reviews the basic characteristics of coral aggregate and mechanical properties and durability of coral aggregate concrete. It also describes the performances of coral aggregate concretes with mineral admixture or fiber reinforcements. The paper ends with a concise discussion upon the existing problems and the future research directions.
