Micro Silica By Gongyi Jinshi Refractory Co., Ltd.

With a sole aim in delivering quality products, we are the prominent Exporter & Supplier of Micro Silica in Gongyi, Henan, China.
Physicochemical Properties:
1, Micro silica appearance: whitei Refractoriness > 1600 a i Bulk density: 200 to 250 kg / m3.
2, Micro silica fineness: 90% fineness of 0.1I m; average particle size of 0.1 ~ 0.2I m, specific surface area: 20 ~ 28m2 / g. Micro silica fineness and specific surface area is 80 to 100 times of that A of cement, 50 to 70 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.
A
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.
