Compressive Strength of Self Compacting Concrete Using Fly Ash and Micro Silica
Abstract: Microsilica is a very fine pozzolanic material, composed of amorphous silica or ferrosilican produced by electric arc furnaces as a byproduct of the production of elemental silicon or ferrosilicon. When microsilica used in concrete, it acts as a cementitious materials. The small microsilica particles fill space between the cement past matrix and aggregate particles. Microsilica also combines with calcium hydroxide to form additional calcium hydroxide through the pazzolonic reaction. Both are these reaction results in a denser, and less permeable materials. Microsilica is specifically used for self compacting concrete and high performance concrete.
