Because of its high activity, water-reducing and reinforcing properties, micro-silica fume plays an important role in the construction cement mortar concrete industry. Therefore, it is widely used in construction, metallurgy, chemical industry, cement and other industries. The raw silica fume is lighter, transportation is more difficult and cost is high.…

As an admixture, silica fume has been widely used in the preparation of high-strength concrete. It can reduce the use of cement clinker. Because of the strong activity of silica fume, pozzolanic reactions and micro-aggregate filling effects can occur in the concrete. The incorporation of silica fume in high-strength concrete…

Densified silica fume is produced by treating undensified silica fume to increase the bulk density up to a maximum of about 400 to 720kg/m . This increase in bulk density is usually accomplished by tumbling the silica-fume particles in a silo, which causes surface charges to build up. After the…
