The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having nearly perfect basal are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheetlike arrangement of its atoms.
The main forms of mica, as a product, are as mica roll, mica sheets, mica tubes and mica components. Mica roll laminates come as pure mica, glass mica or combi laminates. Each comes in different grades of thickness, and display superior slip pane thermal conductive characteristics. Glass mica has added robustness from its glass fibre reinforcement.

Strength – The concrete strength is very high in m sand compared to river sand used in concrete. Because it is manufactured from the rock stones, it will have good compressive strength. Quality of concrete – We mostly experience concrete bleeding segregation, which will lead to concrete crazing while pouring the concrete Shrinkage.
Finer than fly ash, this pozzolan increases strength and density, reduces concrete permeability Microsilica is a mineral admixture composed of very fine solid glassy spheres of silicon dioxide. Most microsilica particles are less than 1 micron ( inch) in diameter, generally 50 to 100 times finer than average cement or fly ash particles.
