Micro Silica is a reactive pozzolan which is used to improve the strength and durability of concrete. It is a byproduct of the production of silicon metals and alloys.

Micro-silica concrete is a highly effective construction material. It has a number of industrial applications and is one of the most popular construction materials in use today. Besides providing early strength and high lateral surface area, it also offers high electrical resistivity.

It can be added to concrete to enhance its strength and durability, while maintaining the integrity of the structure. Adding Micro-silica reduces the permeability of concrete. This decreases the time it takes for corrosive chemicals to enter the concrete.

Microsilica is used to increase the compressive, bending, and flexural strength of concrete. It also has a positive effect on the flow of water in concrete. As a result, it reduces the bleed-water channels that cause cracking.

In addition to its durability, micro silica is a cost-effective substitute for cement. A 5% micro silica content in concrete has been shown to improve bending, compressive, and flexural strength by 10%.

Micro-silica for concrete is produced from ferrosilicon alloys. These products are then processed into slurries or micropellets. The slurries are then mixed with water and cement. Because of its pozzolanic properties, it helps to stabilise the pore structure of the paste.

Micro-silica is a pozzolanic, non-crystalline polymorph of silicon dioxide. It contains trace contaminants such as calcium, iron, and magnesium.

Using micro-silica in concrete will allow the formation of a compact, hardened, elastomeric material. It will also enhance the anti-cavitation ability of the concrete. Moreover, it protects the embedded structures of the concrete from aggressive agents.
