1. What is the silica fume

Silica fume, also called as micro silica, silica dust, which is a by-product of producing silicon metal or ferrosilicon alloys.

Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2). Because of its fine particles, large surface area, and the high SiO2 content,



silica fume is a very reactive pozzolan when used in concrete

a. Silica fume admixture used in high performance concrete

Performance:

Can prevent concrete from the corrosive chloride and seawater

Improving the high resistivity of concrete

Improving the wear resistance of building, like flight runway, aircraft carrier deck, high speed way

Can improve strong chemical corrosion resistance



b. Silica fume admixture used in high intensity concrete

Performance:

Improving the compressive strength of concrete to **0MPa

Improving the modulus of elasticity of concrete to ****0MPa

Can make the flexural strength of flight runway to *4MPa with *8days

Apply for projects and precast assault with high early strength



c. Silica fume admixture used in shotcrete concrete

Performance:

Reducing the shotcrete rebound rate loss to *0%

Improving the construction efficiency, one sprayed layer thickness up to *2inch

Strength the resistivity and lower the permeability

Can retain compressive strength and flexural strength
