Description
Bemsun microsilica, a good admixture for concrete.
1. Microsilica
performance in concrete
a. microsilica admixture is usd in 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. Microsilica admixture is 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. Microsilica 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

3. Microsilica
Concrete Admixture application
Microsilica apply in concrete will help to build a durable future
into the infrastructure of seaport, high building, reservoir dam,
Railway, driver road, bridge, metro, tunnel, airport runway, coal
lane and etc
