microsilica for water glass【价格 厂家 供应】-pg电玩城

microsilica industry: can replace quartz mine, production module is 4.

microsilicais a high value-added by-product of silicon and ferro-silicon alloy in metallurgy industry. it is often used in refractory materials and cement concrete as well as grouting materials and mortar. the microsilica in concrete has volcanic ash reaction, and the silicon-rich gel formed by hydration of microsilica is stronger than ca(oh)2 crystal and works together with cement hydrated gel c-s-h.

microsilica has relatively high activity. at the same time, it is applied to fill the void of particles in cement concrete to increase volume density, increase strength and reduce porosity, so as to reduce water and enhance strength. this is the working principle of micromicrosilica.

the content of micro microsilicais 85% of >, and the carbon of micro silicacontains the adsorption part of the aerator in the concrete. therefore, the burning loss <=7%(controlling the carbon and water content) is again that the fineness of microsilicashould be controlled at 45 um, the grain size is large, and the sieve component is below 10%.

previously calculation: some scholars and experts to the amount of 15% of microsilicato replace cement, cement particles in the concrete and the proportion of microsilicaparticle number is 20, 00000, thus the microsilicais a kind of super fine powder material, the increase of concrete strength, is the key to improve the bond strength between cement paste and aggregate, can reduce fresh water, prevent moisture under the aggregate surface, thus improve the interfacial transition zone, compactness and reduce the thickness of interface transition zone.
