Application:

1.Micro silica in Concrete:
(1)Micro silica Makes high-grade concrete effectively enhances the strength  and pumpability of strong concrete. 
(2)Making high crack-resistance, self-waterproofing concrete, Micro silica be used in the subway, tunnel and basement of high-rise structures.
(3) Used in maritime works and chemical industry. Owing to the compactability, Micro silica can prevent effectively sulphate and chlorine ion from osmosizing and eroding Avoid the steel corroding in armoured concrete (RC), lengthen the life-span of concrete.
(4)Micro silica used in the construction item under water, such as pier, huge dam and drilling platform.
(5)Microsilica used in road surface concrete of expressway and large-scale bridge.
2.Micro silica in refractory:
(1)Micro silica Enhancing the fluid of pouring refractory, reducing the volume of used water, be easy to shape, and raising the production efficiency.
(2) Micro silica is a highly effective pozzolanic material, so it's easy to come into being Mullite Phase, under the premise that Al 2 O3 exists, enhance elevated temperature strength and thermal shock of refractory.
