self compacting concrete mix design excel sheet

A mix proportion was proposed by Okamura and Ozawa for SCC where the water/powder ration is to be adjusted and aggregate and fine aggregate contents fixed with self-compatibility achieved with the addition of plasticizer dosage. SCC mixes must have three important properties: flow under its own weight to completely fill intricate and complex forms, under its own weight the ability to pass through and bond congested reinforcement and high segregation resistance to aggregate. Formulating SCCs is a compromise between adequately high fluidity to ascertain good casting and an adequate consistency to eschew phase separations quandaries (segregation or bleeding). Self-compacting concrete (SCC) is a development of conventional concrete, where the use of vibrators for compaction is no more required.

The shortcoming in conventional concrete such as poor flow faculty and subsequent segregation quandaries leading to poor culminating and delayed construction time led to the development of self-flowing or self levelling concrete. Concrete is defined in the wider perspective as ' any product or mass made by the use of a cementing medium'' and the medium is the product of hydraulic cement and water reaction. Concrete is an essential material in the building industry with world consumption estimated close to 25 billion tons every year and it is considered as the widely used material in the world.
