Microsilica

Densified Silica-Fume Admixture

Microsilica is a densified powder admixture with pozzolanic action, to be used in combination with plasticizers and superplasticizers for high-quality mortars, grouts and concrete.

Microsilica complies with the provisions and specifications of ASTM C1240 and AASHTO M307.

Microsilica is an amorphous silicon dioxide (silica) consisting of sub-micron spherical primary particles and agglomerates of these. The material is highly reactive in cementitious and ceramic bond systems.

The average diameter of a Microsilica sphere is about 0.15 micron. Although some of the spheres exist as single entities, most of them form primary agglomerates. The size of these may vary between 0.1 and 1 micron. This rather wide particle size distribution contributes to high packing efficiency.
