Micro Silica For Concrete

Significantly improve the pressure resistance, compressive strength, impermeability level, corrosion resistance, impact resistance and wear resistance.

It has the effect of locking water, preventing concrete segregation and bleeding, and greatly reducing the frictional resistance of concrete pumping.

Significantly increase the service life of concrete. Under extreme conditions such as chlorine salt environmental pollution corrosion, potassium thiocyanate corrosion, high ambient humidity and other extreme conditions, the durability of concrete can be doubled or even multiple times increased.

Significantly reduce the amount of ash sprayed out of concrete and castables, and increase the thickness of each spray layer.

Micro silica fume is an essential active ingredient in high-strength concrete and has been used in C150 concrete engineering projects.

Microsilica fume has about 5 times the effect of cement. It can control costs and improve durability when used in general concrete and low-cement castables.

Reasonably avoid the generation of concrete-alkali aggregates.

Improve the high density of cast-type refractory insulation materials. When coexisting with Al2O3, it is easier to generate a zirconium corundum phase, which improves its high-temperature compressive strength and thermal shock resistance.

Microsilica powder has a strong volcanic magma effect. When mixing cement concrete, it can produce a secondary hydration reaction with the cement hydration substance Ca(OH)2 to produce gelling substances, fill the cement and stone structure, and improve the slurry. The external economic structure improves the physical properties and durability of the hardened body.

Microsilica fume is amorphous spherical particles that can improve the bonding performance of cement concrete.

The size of the uniform particles of microsilica fume is relatively small and has good cleaning effect. It can be filled in the gaps between cement particles to improve the strength and durability of concrete.
