An Experimental Study on Steel Fibres Reinforced Self Compacting Concrete using Metakaolin as Partial Replacement of Cement

A Self Compacting Concrete (SCC) is a concrete that can flow and completely fill the formwork under its own particular weight, simultaneously maintain its homogeneity regardless of the fact that congested reinforcement is available and later accomplishes complete compaction without any need of external vibration (The Concrete Society and BRE, 2005). Due to this reason concrete is replaced by Metakaolin in various percentages of 0%, 2.5%, 5%, 7.5% and 10% with additional percentages of steel fibres as 0%, 1%, 2%, 3% and 4%, respectively. The size of cube specimen is 150×150 which is used for compression test. The size of cylinder specimen is 150mm diameter and 300mm height for tensile test. Standard prisms of size 100mm x 100mm x 500mm are tested under two point loading to study the flexural strength. The compression, tensile and flexure tests are conducted for the specimens.
