Considering the economy and durability of the present concrete structures, the quality and the density of concrete as well as the compaction of the concrete are main parameters. For this, Self-Compacting Concrete (SCC) offers new possibilities and prospects. Self Compacting concrete is a recently developed concept in which the ingredients of the concrete mix are proportioned in such a way that it can flow under its own weight to completely fill the formwork and passes through the congested reinforcement without segregation and consolidate without any mechanical vibration. An attempt has been made in the investigation reported in this paper to study fresh, hardened properties and stress- strain behavior of High Strength SCC(M70).An improvement in the compressive, tensile and flexural strengths in SCC mix was observed. Complete Stress–strain behaviour has been presented and an empirical equation is proposed to predict the behaviour of such concrete under compression.
