Abstract

 Experimental studies were conducted on fundamental properties, shrinkage properties, thermal properties, and wear properties of self-compacting concrete mixed with seawater and limestone aggregate derived from corals assuming use on isolated islands. As a result, the concrete using this aggregates with many voids had excellent fluidity, moderate segregation resistance, and the same strength development as when using ordinary aggregates. In addition, shrinkage and thermal expansion coefficient were smaller than that of concrete using ordinary aggregate. Furthermore, even when coral aggregate was used, abrasion resistance of concrete equivalent to that when using ordinary aggregate could be secured by setting the water cement ratio and unit coarse aggregate volume small.
