SELF COMPACTING CONCRETE USING INDUSTRIAL BY-PRODUCT

Civil Engineering

Concrete is a mixing of binding material, fine aggregate, coarse aggregate and finally water. Concrete is normally use in the frame structure. But there is some limitation like self-compaction, surface finishes, maintains strength at congested area. Due to this limitation we are trying to make self-compacting concrete. SCC is considered a concrete that can be placed and compacted under its own weight without any vibration effort, assuring complete filling of formwork even when access is hindered by narrow gaps between reinforcement bars. Self-compacting concrete has ability involves not only high deformability of paste or mortar, but also resistance to segregation between coarse aggregate and mortar when the concrete flows through the confined zone of reinforcing bars. In recent years, self-compacting concrete (SCC) has gained wide use for placement in congested reinforced concrete structures with difficult casting conditions. For such applications, the fresh concrete must possess high fluidity and good cohesiveness.
