Refractory material usually uses unencrypted micro silicon powder. At present, besides in casting refractory material widely using, unencrypted micro silicon is applied extensively in the fused and sintered refractories.

High Performance Concrete (HPC) containing silica fume has been identified as one of the more important advanced materials necessary in the effort to rebuild the nation's infrastructure. In addition to increased strength and enhanced durability, it produced with silica fume delivers increased toughness, increased resistance to abrasion, corrosion and chemicals, sustainability and life-cycle cost efficiencies. High Performance Concrete Services

any volume of concrete in which a combination of dimensions of the member being cast, the boundary conditions, the characteristics of the concrete mixture, and the ambient conditions can lead to undesirable thermal stresses, cracking, deleterious chemical reactions, or reduction in the long-term strength as a result of elevated concrete temperature due to heat from hydration.

Silica fume is a by-product of the silicon metal/ferrosilicon alloy industry. Collected in baghouse filters, it is a very fine pozzolanic material. The addition of silica fume to concrete was first tested in Norway in the 1950s. Although positive results were recorded in terms of improved strength, at that time no method of retaining large quantities of silica fume was available, preventing its industrial-scale use.

Making full use of micro silica fume concrete early strength, high strength, wear resistance, can build the high grade highway, airport runway, highway tunnel and road repair projects. The construction of roads with silica fume can achieve 25Mpa compressive strength for 12 hours, improve 1 times of abrasion resistance, and 24 hours compressive strength up to 37Mpa, exceeds the design requirement of C20 concrete.

Microsilica or Silica Fume improves the performance of concrete and mortar formulations. It acts physically to optimize particle packing of the concrete or mortar mixture and chemically as a highly reactive pozzolan.
