We wish to inform you that we have invented a new micro silica powder that has a real chemical effect on concrete, cement and other products. Our factory can make different analyses, purity, density, size as per customer's specifications. Our micro silica powder with silicium criterion of 86 to 94 per cent meets Iranian Standards of 13278 and ASTMC1240 with confirmation from ministry of Road, Housing and Urbanization department. Our product is exported to EU and Asian countries through our offices in Oman, Turkey, Dubai and has got EU approvals. This material is used to protect concretes against corrosion, pressure and electricity conduction and potentially applicable in constructions, hard-melts and polymer industries. Micro Silica is used as a pozzolan material or a part of Portland cement mixture or mineral additives in concrete. Commercially, micro silica is limited to 15-20% of the total mass of cement materials. This amount of micro silica is usually having useful effects in economy, efficiency and cost of concrete, being essential for increasing durability against sulphate attacks, Alkaline Silica extension and thermal cracks.
