Application of Microsilica
The American Concrete Institute (ACI) defines Microsilica as “very fine non-crystalline silica produced in electric arc furnaces as a by-product of production of elemental silicon or alloys containing silicon” (ACI 116R). It is different from pulverized silica. Microsilica, also known as silica fume.>
