Amorphous silicon powder (scientific name " microsilica," Micro silica or silica powder), in the smelting of ferro silicon and industrial silicon, silicon through the flue gas emitted by steam oxidation, the specially designed filter collected the amorphous powder like silica (SiO 2).Microsilica fume average 0.1-0.15 μ m in diameter, the size of several cement average 1.0%. Surface area for the 15-27 m 2 / g, with strong surface activity.
When it is used in concrete, it acts as a filler and as a cementitious material. The small Silica fume particles fill spaces between cement particles and between the cement past matrix and aggregate particles. Silica fume also combines with calcium hydroxide to form additional calcium hydrate through the pozzolanic reaction. Both of these actions result in a denser, stronger and less permeable material.

Our products high meets ASTM1240, SGS , ISO9001, tc stardards.
The uses for RW silicon carbide abrasive powder in concrete fit into general categories of enhancing mechanical properties, improving durability, enhancing construct ability.
1) Making high-grade concrete effectively enhances the strength and pump ability of strong concrete.
2) Making high crack-resistance, self-waterproofing concrete, be used in the subway, tunnel and basement of high-rise structures.
3) Used in maritime works and chemical industry. Owing to the compact ability, it can prevent effectively sulphate and chlorine ion from osmosizing and eroding Avoid the steel corroding in armoured concrete (RC), lengthen the life-span of concrete.
4) Effects on high-early strength concrete and strong concrete.
5)In project item for water conservancy and bridge, the concrete not only needs basic quota mentioned above, but also its wear-resistant quality and abrasion resistance.Thus, adding silicon carbide abrasive powder is necessary.
6) Effects on short creting-lined concrete for support in tunnel, subway, and large-scale foundation ditch.
7) Used in the construction item under water, such as pier, huge dam and drilling platform.
8) Used in road surface concrete of expressway and large-scale bridge.
(1) Silica fume can be blended into cement and concrete to improve the quality of concrete.
(2)It can be used as addition agent in the fireproofing material. Silicon fume has high fluidity, high strength.
(3)It is the adhesive of metallurgical pellet.
1.Regular products packing with a multilayer woven plastic ton bag each ton. Or with small bags(20/25/50kg) then into a ton bag.
