  • Microsilica in Concrete PPT Silica Fume for Sale

    Microsilica in Concrete PPT. As the molten metal is produced, a silica-based gas is emitted. This gaseous fume, as it rises, cools rapidly and forms extremely minute,Amorphous, spherical particles. The micro silica fume is collected in a bag house, a system for filtering the hot air and gases vented from the furnace.

  • Effect of Cement Replacement by Silica Fume and Fly Ash

    The replacement level of silica fume is generally low at about 10%. When SF is used in concrete mix, its introduction affects the physical arrangement of the system, particularly near the aggregate surface where porosity exists. Silica fume starts reacting at the early stage of hydration process.
