Micro Silica

タイトルまたは説明

Silicon Powder Physicochemical Properties:

1, Micro silica appearance: white；Refractoriness > ***0 ℃； Bulk density: **0 to **0 kg / m3.

2, Silica fume fineness: *0% fineness of 0.1μm; average particle size of 0.1 ~ 0.2μm, specific surface area: *0 ~ *8m2 / g. Fineness and specific surface area is *0 to **0 times of that  of cement, *0 to *0 times of fly ash.

3, Micro silica particle morphology and mineralogical structure: Due to the surface tension of the phase change, micro silica fume forms into amorphous phase amorphous spherical particles with smooth surface, or a plurality of ball particles stick together.

Micro silica fume is a high activity pozzolanic material with large surface area. Micro silica in materials will play the role of lubrication with the tiny spherical body.
