 Microsilica (Semi-Densified) |
Product Description
Microsilica, is a very fine pozzolanic material. This product comprises microscopic particles collected by filters 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 is between 0.1um and 0.15um. Its specific surface area is between 15m² /g and 27m² /g, which have superpower surfactivity.
Microsilica can be used in a variety of cementitious products such as concrete, grouts and motars as well as refractory, ceramic, etc. Applications.
