96%min high purity micro silica powder for refractory
1.Enhancing the fluid of pouring refractory, reducing the volume of used water, be easy to shape,and raising the production efficiency.
2.Because of its untramicrostructure for gap filling, the compact and intensity of refractory gain rising by a wade margin.
3.Silica fume is a highly effective pozzolanic material, so it's easy to come into being Mullite Phase, under the premise that Al2O3 exists, enhance elevated temperature strength and thermal shock of refractory.
Silica Fume in Concrete
1. Making high-grade concrete effectively enhances the strength and pumpability of strong concrete.
2. Making high crack-resistance, self-waterproofing concrete, be used in the subway, tunnel and basement of high-rise structures.
3. Used in maritime works and chemical industry. Owing to the compactability, it 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. Used in the construction item under water, such as pier, huge dam and drilling platform.
5. Used in road surface concrete of expressway and large-scale bridge.
