Study of mix design method for self-compactable high performance concrete with lime stone powder
Sakata Kenji; Ayano Toshiki
Abstract:Self-compactable high performance concrete, which can be poured in casting forms without any compaction, is of importance to many engineers because of the reliability of economic and efficient construction of concrete structures by utilizing very little manpower for placing of void free concrete. By the mix design method proposed in this paper, it is possible to choose the required average strength, water content and sand/aggregate ratio to suit special and particular conditions of concrete structures under various environmental conditions. Key Words:high flowability, resistance to segregation, slump, slump flow, lime stone powder, mix design
