Abstract

Shirasu is a name of pyroclastic flow deposits called in the southern part of Kyushu. This paper presents a production method of wet consistency concrete using Shirasu as fine aggregate (Shirasu concrete) and its properties. It was necessary for producing Shirasu concrete to add a lot of amount of air-entraining high-range water reducing admixture and reduce sand-total aggregate ratio. On the other hand, the compressive strength of Shirasu concrete was larger than that of concrete using land sand as fine aggregate. In addition, Shirasu concrete demonstrated superior performance on resistance against neutralization and development of strength of concrete in structure.
