Product Description
Microsilica is also called silica fume or agglomerated silica fume. When iron alloy is used to smelt ferrosilicon and industrial silicon (metal silicon), a large amount of highly volatile SiO2 and Si gas is generated in the ore furnace, and the gas is discharged and air. Rapid oxidation and condensation precipitation. It is a by-product of large-scale industrial smelting. The whole process needs to be recycled by dust-removing environmental protection equipment. Because of its low density, it needs to be encrypted with encryption equipment. Microsilica is a new type of concrete admixture. The main component is si02, the average particle size is 0.1¦Ìm, which is 1% of cement. The color ranges from light gray to carbon black. It has pozzolanic reaction characteristics and can be hydrated to form a silicon-rich gel with higher strength than calcium hydroxide crystal. Working with cement hydrating gel CSH, it is a highly active hydraulic cementitious material, which is added to make the physical properties of concrete greatly improved. Highly active micro silicon powder is an ideal admixture for bridges, dam concrete, high wear resistance, high i***ct concrete, shotcrete and so on. In recent years, micro-silica powder has also begun to be widely used in various oil fields. Especially in oil field cementing, due to the use of micro-silica powder, the high temperature strength decay performance of the mud solidified body is improved. It is widely used in high temperature deep wells, geothermal wells and thermal wells. The general usage is 8%-15%.
