High Quality Micro Silica Concrete 85%-97%

These High quality micro silica concrete 85%-97%, also called silica fume or micro silica, is a byproduct of producing silicon metal or ferrosilicon alloys. Silicon metal and alloys are produced in electric furnaces. The raw materials are quartz, coal, and woodchips. The smoke that results from furnace operation is collected and sold as silica fume, rather than being land filled. Micro Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2), its average granule diameter is 0.15~0.20 Aum,specific surface area is 15000~20000 m2/kg, and it has extremely strong surface active. Micro silica fume can be used in a variety of cementation products, such as concrete, grouts, and mortars as well as elastomeric, polymer, refractory, ceramic and rubber applications. 2.Physican and chemical properties: SiO2(Silicon Dioxide):min97% C(Carbon):max0.7% Fe2O3 (Iron Oxide):max0.1% Al2O3(Aluminium Oxide):max0.3% CaO(Calcium Oxide):max0.3% MgO(Magnesium Oxide):0.2% K2O(Potassium Oxide):0.3% Na2O(Sodium Oxide):max0.2% P2O5(Phosphorus Pentoxide):max.0.1% SO3(Sulphur Trioxide):max.0.2% Cl (Chloride):max.0.1% Moisture Content(H2O):max.0.5% Loss on Ignition(L.O.I):max0.5% Percent Retained On 45I m (325 sieve):max0.5% Bulk Density:250-300kg/m3 and 450-600kg/m3 Capacityi 3600Tons/Month
