Product Description

MS 085 is dry Silica Fume powder, a very fine pozzolanic material. This product comprises microscopic particles collected by filters downstream from the smelting process in silicon or ferrosilicon alloys. In use, MS 085 can increase the density and wear resistance for concrete and other cementitious materials and extends the service life. The median diameter of silica fume is 0.1 ~ 0.15μm. Its specific surface area is between 15 ~ 27m2/g, which gives superpower surface activity.

MS 085 can be used in a variety of cementitious products such as concrete, grouting mortars and other applications like refractory, ceramic etc.
