Product Description:
Silica Fume Concrete collected and packed from silicon metal or ferrosilicon factories directly, the automatic and integrated production process guarantees the consistent quality. Microsilica are classified as various grades and can be used in Concrete, Oilwell cement, Refractory and Fertilizer industries.

Silica Fume Concrete ash can fill the pores between cement particles, at the same time with hydration products to produce gel, and alkaline material magnesium oxide reaction to produce gel.
In cement-based concrete, mortar and refractory castable, the appropriate amount of silica ash can play the following role:
a, significantly improve the pressure resistance, anti-folding, anti-seepage, anti-corrosion, impact resistance and wear resistance.
b, with water retention, prevention of segregation, drainage, greatly reduce the role of concrete pump resistance. significantly extend the service life of concrete.
c. Especially in the harsh environment such as chlorine salt pollution erosion, sulfate erosion and high humidity, the durability of concrete can be increased one or even several times.
d, greatly reduce the injection of concrete and pouring material floor ash, improve the thickness of a single spray layer.
e, It is a necessary component of high-strength concrete, has C150 concrete engineering applications.
f, with about 5 times times the effect of cement, in ordinary concrete and low cement castable application can reduce costs. Improve durability.
g, effectively prevent the occurrence of concrete alkali aggregate reaction. 8, improve the density of pouring refractories.
When coexisting with Al2O3, it is easier to generate mullite facies, so that its high temperature strength, anti-thermal vibration enhancement.
China high density of microsilica/silica fume for concrete/ Cement
best price microsilica / silica fume with high quality for concrete bloc
Application area:
1) Concrete or Shotcrete
• Increase its density and strength, improve the performance on its durability,
impact resistance, corrosion resistance, anti-permeability and frost resistance etc
2) Refractory material & Ceramics material
• Greatly improve its density, strength and high temperature performance.
3) Cementitous Repair Products (Mortars & Grouts)
• Low permeability, increase resistance from chlorides, acids, nitrates and sulfate etc
4) Oil Well Grouting
• Increase durability and compressive strength, decrease permeability, better control of gas leakage
5) Concrete Tile, roofing & wallboard,panels
• Lightweight and improve the strength
6) Polymers & rubber product
7) other application, such as waterglass industry, thermal insulation material etc.
