Self Compacting Concrete
´ Fresh concrete that can flow around reinforcement and consolidate within formwork under its own weight that exhibits no defects due to segregation or bleeding.
´ The guiding principle for this type of concrete is that the sedimentation velocity of a particle is inversely proportional to the viscosity of the floating medium in which the particle exists.
Benefits of SCC
´ Faster construction
´ Reduction in site manpower
´ Safer working environment
´ Improved aesthetics
´ Easier placing
´ Improved durability
´ Two anchorages of Akashi-Kaikyo (Straits) Bridge, Japan. The volume of the cast concrete in the two anchorages amounted to 290,000 m3
´ The highest use of SCC in India was done at Delhi metro project. About 10000 m3 of SCC has been Used.
´ At Kaiga nuclear power plant, SCC of Characteristic strength 30 MPa was used.
