Abstract

In self-compacting concretes containing fly ash, the upper replacing ratio limit of fly ash to a cementitious material has been stipulated by the Japan Society of Civil Engineers (JSCE) and the Architectural Institute of Japan (AIJ). This study investigates the proposal of the mix design, the effect of the replacing ratio of fly ash on the strength and the durability of concretes complied with the self-compacting rank 2, and the ability of construction according to practical construction work from the viewpoint of the effective uses of fly ash. The results obtained are as follows : The strength and the durability of the self-compacting concretes containing high volume fly ash are influenced by various replacing ratio of fly ash. The self-compacting concrete at 50% of the replacing ratio is excellent workability and compaction at the site of construction.
