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.

Application industry

Iron And Steel Industry

Refractory material is an important material used in the steel industry. It is mainly used in the lining of steelmaking furnaces, ironmaking furnaces, bearing and transporting ladles of ladles for slag and slag, As well as the lining of the flue and blast furnace body that conducts the heat. So, simply, we can think of it as a structural material.

Glass Idustry

Refractory material is the main building material of glass melting furnace, which has the decisive influence on glass quality, energy consumption and even product cost. The development of glass melting technology relies heavily on the progress and quality improvement of refractory manufacturing technology.
