Properties of High Performance Self Compacting Concrete In Fresh and Hardened State

Increasing concrete strength is always one of the main scopes of concrete technology. Because of high viscosity of cement paste, concrete compaction performed difficulty. To improve the compaction characteristics of the concrete the idea of adding coarse aggregate and silica fume was developed. The first tests showed a good workability of the fresh concrete and a good self compacting ability. Test results show better workability, shrinkage tendency and the modulus of elasticity.
