Silica Fume Concrete is widely used in concrete and fiber cement industries. In addition to its pozzolanic properties its is also a very good filler due to its particle size. These combined properties lead to an extended life expectancy in corrosive environments (resistance to chlorides acids and sulphates) and improved strength.

Concrete. Because of its extreme fineness and high silica content silica fume is a very effective pozzolanic material. Standard specifications for silica fume used in cementitious mixtures are ASTM C1240 EN 13263. Silica fume is added to Portland cement concrete to improve its properties in particular its compressive strength bond strength and abrasion resistance.
