Abstract

Significant amount of time has been put into research work to bring into use the day to day waste producedand other by product materials whether agrarian such as Rice Husk Ash or industrial such as Silica Fume.As a result they have created a space as supplementary cementing materials (SCM) to be not only beneficialto concrete properties but also reducing the pressure of waste decomposition and at the same time beingeconomical and easily available. This review was done to summarize the various research work publishedon the effects of Rice Husk Ash and Silica Fume on the character of concrete. At optimum range of 10% to20%, Rice Husk Ash reduced the workability but improved the compressive strength and durability ofconcrete. Silica Fume at an optimum range of 10% to 15% improved the compressive, tensile and flexuralstrengths of concrete and also enhanced its resistance to sulfate attack. There is scope for further researchthat be performed on ultra-fine particles of Rice Husk Ash and Silica Fume and study their influence onconcrete.
