Nanosilica
SF and NS are synthesized by different chemical procedures. SF (also known as microsilica) is a by-product of the smelting process of silicon metal and ferrosilicon alloys used for steel and aluminum production (Silica Fume Association, 2005). In electric arc furnace, raw materials (quartz and coal) are smelted at high temperature.

The experimental program was designed to investigate silica fume as partial cement replacement in concrete. The replacement levels of cement by silica fume are selected as 5%, 10%, 15%, 20%, and 25% for standard size of cubes for the M30 grade of concrete. The specimens of standard cubes (150 x 150 x 150 mm), was casted with silica fume.

How Microsilica Improves Concrete
Addition of microsilica to a concrete mix alters the cement paste structure. The resulting paste contains more of the strong calcium-silicate hydrates and less of the weak and easily soluble calcium hydroxides than do ordinary cement pastes. Because the microsilica particles are so small they disperse among and separate the cement particles.

Effects of rice straw ash and micro silica on
As microsilica is a costly material, its inclusion in the concrete will increase the construction cost of the structure. Therefore a material was needed that is economical as well as it also imparts strength to the concrete. Rice straw ash has all the properties of a better pozzolan, and it is much cheaper than most of the mineral admixtures.
