珊瑚岛很小，分散在世界各地的深海中，距离大陆数百公里。在这些岛屿上进行建筑活动，珊瑚木瓦和珊瑚砂是当地可获得的主要材料。一项审查表明，只有少数调查已经进行了珊瑚骨料和混凝土的性能与他们。本文讨论了珊瑚木瓦和珊瑚砂的物理、化学和力学性质的系统研究结果。通过与普通花岗岩碎骨料和河砂试验结果的对比，研究了它们作为混凝土骨料的适用性。对不同水灰比的普通骨料混凝土和珊瑚混凝土的工作性、密度和抗压强度特性进行了比较和讨论。
Coral islands ave tiny and ave scattered in deep seas throughout the world, hundreds of kilometres away from the mainland, For construction activities in these islands, coral shingles and coral sand ave the main locally available materials. A review indicates that only a few investigations have been undertaken on the properties of coral aggregates and concrete made with them. This paper discusses the results of a systematic investigation of the physical chemical and mechanical properties of coral shingles and coral sand. Their suitability as aggregate for concrete making has been studied through comparison with the results of tests on conventional crushed granite aggregate and river sand. The workability, density and compressive strength characteristics of different nominal mixes of conventional aggregate concrete and coral concrete with various water-cement ratios have been compared and discussed.
