microsilica powder mixed with cement concrete can be a very good after filling in cement granular space, make the slurry more dense, it also combined with free ca (oh), form a stable compound calcium carbonate water 2 cao, si02, h2o, the hydrate gel strength higher than that of ca (oh) crystals, mainly displays in:
u increase intensity: make the concrete compressive strength, flexural strength greatly increased, mixed with 5-10% of microsilica, can improve the compressive strength of 10-30%, the flexural strength increased by more than 10%.
expansion increased density: the anti-permeability performance increased by 5-18 times, and the anti-seepage ability increased by more than 4 times.
anti-freezing properties: the relative elastic modulus of micro silicon powder decreases by 10-20% after 300-500 rapid freezing cycles, while that of ordinary concrete decreases by 30-73% after 25-50 cycles. tensile strength: silica powder shortens the induction period of concrete and has the characteristics of drought.
anti-scrubbing and cavitation erosion resistance of activated concrete: the anti-scrubbing ability of silica powder concrete is improved by 0.5-2.5 times than that of ordinary concrete, and the anti-cavitation ability is improved by 3-16 times.

microsilica is an industrial additive that works differently when combined with other industrial materials. it is mainly added to concrete, cement, refractory, paint and other macromolecular materials. it can also change the properties of porcelain products. in the construction of road, adding silica powder can improve the permeability and wear resistance of concrete pavement. it can also be used as a reinforcing material for organic compounds, since its composition is very similar to that of white carbon ash, and can be used as a filler in polymer materials such as rubber, paint and paint. it can also be used as an anti-caking agent in the fertilizer industry.
