Silica fume can be used either as a densified or undensified powder, a slurry, as combination at the concrete mixer, or part of a factory-blended cement. Generally, the comparisons are made against a concrete made with 100% CEM I (Portland cement). The following terms are used with specific meanings: – blending: mixing together cementitious components

920 silica fume can fill the porosity of the cement particles, and at the same time generate gel with hydration products, reacts gel with alkaline material- magnesium oxide. In concrete and mortar, mixed with right amount of silica fume, can play a role as follows: 1. Improve compressive strength, bending, anti-permeability, anticorrosive, impact resistance and

Zirconia silica fume is a compound of zirconium dioxide, zirconium oxide melting products. The production of silicon-zirconium off special device which used to collect the silica powder, not only has the general characteristics of sillca, but also a certain amount of zirconia powder. Zirconia silica has a special use in the field of refractories ,
