"Mixture Properties of Self-Compacting, High-Performance Concrete"

The self-compacting concrete, which was developed in 1988 in Japan, can be filled in a formwork without using any vibrators. It is an effective means of ensuring consistent quality in concrete structures, as the human factor in consolidation can be eliminated. This type of concrete has markedly increased deformability without segregation: high deformability is achieved mainly through the use of superplasticizers, while segregation resistance is achieved mainly through viscosity of the mortar or paste components of the concrete. The focus of this study is on experimental assessment of the effects of each component of concrete mixture in self-compacting concrete on the fresh state.
