Rice Husk Ash

Rice Husk Ash generally obtained by burning rice husk (outer portionof rice seed) in a controlled pathway without making any type of exibit environmental pollution.After burning rice husk it can be performed  as a generalized concrete admixture and Sio2 content is very much high.Due to presence of high pozzolonic features it provides high strength and high permeability on concrete.

Rice husk ash contains silica (92% approx),carbon (4%),K2O(2%).so, if proper production is available of rice husk ash would be a good pozzolonic material as a substitute of microsilica.
