silica fume/microsilica for HPC concrete

Microsilica, is a very fine pozzolanic material. This product comprises microscopic particles collected by filters downstream from the smelting process in silicon or ferrosilicon alloys. 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.
