Brand: Silica fume
Model: Silica fume
Silica fume
Silica fume, also known as microsilica, is a byproduct of production of silicon and ferrosilicon alloys. Because of its extreme fineness and high silica content, silica fume is a highly effective pozzolanic material.

Silica fume in concrete:
When add silica fume into concrete materiasl,their strength,abrasion resistance, impermeability, resistance to chlorine ion and sulphate attack. freeze-thaw resistance and durability will be improved a lot.

Application and Usage:
(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, lengthen the life-span of concrete.
(4)Effects on high-early strength concrete and strong concrete.
(5)In project item for water conservancy and bridge, the concrete not only needs basic quota mentioned above, but also its wear-resistant quality and abrasion resistance.
(6)Effects on shotcreting-lined concrete for support in tunnel, subway, and large-scale foundation ditch.
(7)Used in the construction item under water, such as pier, huge dam and drilling platform.
(8)Used in road surface concrete of expressway and large-scale bridge.



Silica fume in refractory:
Silica fume in refractory enhancing the fluid of pouring refractory, reducing the volume of used water, beeasy to shape, and raising the production efficiency. Because of its untramicrostructure for gap filling, the compact and intensity of refractory gain rising by a wade margin.
Silica fume in refractory 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.

Usage:
(1)Silica fume in refractory is used in unshaped refractories
(2)Silica Fume in refractory is used ingunned refractory materials to improves adhesion in castables and minimizes rebound loss
(3)Silica fume in refractory is used in shaped refractories
(4)Silica fume in refractory has the function of high reactivity which improves ceramic bonding in the high alumina and magnesite.Then the firing temperature can be reduced ,the strength, abrasion resistance and chemical resistance may also be improved
