Optimum Replacement of Cement by Rice Husk Ash in conventional Concrete
Gupta Priyanka,  Patel Bina B,  Zala Kartik
In every year approximately 12 million tonne of peddy produced in India this gives around 24 milliontonnes of rice husk and 4.4 million tonnes of rice husk ash every year, major 3 use of rice husk ash in steel, cement & refractory bricks industries. this r.h.a is a great environment threat causing damage to the land and the surrounding area in which it is dumped lots of way are being through of for disposing them by making commercial use of this r.h.a. R.H.A is a good pozzolan. this super pozzolana can be used in a big way to make special concrete mixes .these is a growing demand for fine amorphous silica in the production of special cement and concrete mixes, high performance concrete, high strength, low permeability concrete .concrete for use in bridge, marine environments nuclear power plants etc.in this project evaluate how different contents of RHA added to concrete may influme its physics of mechanical properties. sample cube were tasted with different percentage of rha and different w/c ratio ,replacing in mass the cement properties like compressive strength ,water absorption and slump retention were evaluated.
