- Synopsis:
- In self-compacting concrete containing fly ash, the upper replacing raio 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 investigated the proposal of the mix desing, 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 ofconstruction.
