Microsilica

Microsilica, this product comprises microscopic particles collected by filers downstream from the smelting process in silicon and ferrosilicon plants. Adding it to concrete and other materials, increases their density and wear resistance, which extends the life of structures.  Microsilica stands'average diameter between 0.1um and 0.15um.lts specific surface  is between 15m2/g and 27m2/g,which have superpower surfactivity. In accordance with our microsilica fume SiO2 content of the indicators, the product will be as follows: 85% 88% 90% 95% 98%of the five specifications.
