उत्पाद विवरण
Micro silica is a grey, fine powder that finds use in concrete production. There are many benefits of using this powder into the mixture, which can be high strength concrete, self-compacting concrete and waterproof concrete. The affordable powder when added as a prime additive often reduces the weight and cost of concrete slabs. The concrete slabs produced are more durable against acidic water. It enhances compressive strength, reduces permeability, improves bond, minimizes bleeding and resists chemical, abrasion, corrosion and sulphate.
