Concrete is the most widely used construction material because of its mould ability into any required structural form and shape due to its fluid behavior at early ages. Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Through compaction using vibration is normally essential for achieving workability, the required strength and durability of concrete. Inadequate compaction of concrete results in large number of voids. Affecting strength and long term durability of structures, self compacting concrete (SCC) provides a solution to these problems. And it is able to compact itself without any additional vibration. In this concrete, cement replacement with some material like flyash, metakaolin, ground granulated blast furnace slag (GGBS) etc. because to reduce 5-7% of CO₂ emissions in cement and due to the curing of concrete large amount of water is required. To overcome the high consumption of water it is needed to study the self-curing concrete. The cement reacts with water and other ingredients to form a hard matrix that binds the materials together into a durable stone-like material that has many uses. This investigation will shown scientific basis for potential design of SCC materials for concrete structures.
