Cement additive, you can buy price competitive of silica fume
cement additive from global cement additive supplier at
silica-powder.com.
Silica fum is the cement additive, and what is silica fume, let us
know more about it.
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
2. What is the performance for silica fume cemen additive?
a. Cement additive-silica fume - 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. Cement additive - silica fume - 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. Cement additive - silica fume - 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
3. Cement additve silica fume specification
