CE standard microsilica

CE certification is a symbol of safety compliance rather than quality certification mark. It is the main requirement that forms the core of the European directives.

CE standard microsilica:

Microsilica , also called silica fume.it 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.

Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2), its average granule diameter is 0.15-0.20 µm,specific surface area is 15000-20000 m2/kg, and it has extremely strong surface active.

Microsilica 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.

Packaging Detail: 1000kg/bag, 500kg/bag, 400kg with pallet or 25kg/bag
Delivery Detail: within 10days after received LC or payment

Microsilica common standards are ASTM C1240, CSA A23.5, JIS A6207, CAS 69012-64-2, EN 13263, ACI 234R-06, GB
