Product introduction
Microsilica, also known as silica fume, it is a very fine pozzolanic material, composed of
amorphous silica produced by electric arc furnace as a by product of the production of
elemental silicon or ferro silicon alloys. Silica fume 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.
Jihe Microsilica JH85
Microsilica JH85 is a densified dry powder microsilica admixture for portland cement concrete and
mortars.
Microsilica JH85 is a pozzolanic material that consists primarily of fine silicon dioxide particles in a
non-crystalline form.
Microsilica JH85 meets the requirements of ASTM C1240 and contains a minimum of 85% silicon
dioxide (SiO2)
Microsilica JH85: We have three factories in Shanxi, Yunnan and Qinghai Province, China.
Stable quality and reasonable price.
