Hot Selling Microsilica and Good Effect Of Silica Fume in Concrete

Product Detail

  Product Description:                  





Micro silica ,also called silica fume or micro silica, is a byproduct of production silicon metal or ferrosilicon alloys. Silicon metal and alloys are produced in electric furnaces.The raw materials are quartz,coal and wood-chips.The smoke that results from furnace operation is collected and sold as silica fume, silica fume consists primarily of amorphous(non-crystalline) silicon dioxide(SiO2),its average granule diameter is 0.15~0.20um,specific surface area is 15000~20000m2/kg,and it has extremely strong surface active.

Silica fume is a mineral admixture, composed of submicron particles (100 to 150 times smaller than a grain of cement) of amorphous silicon dioxide. Silica fume powder is gray to off-white in color, and is available in several product forms and packaging options.






  Features Characteristics:           




1).Appearance is as grey&white off.

2).High electrical resistivity

3).Low Permeability

4).Superior resistance to chemical attack from chlorides,acids and sulfates

5).Low chloride ion diffusion

6).High reactive Pozzolan

7).High temperature strength

8).Improved stability ingeothermal environment 




 Microsilica in application of concrete                




1)silica fume is ideal for use in structures exposed to chemical and environmental attack.

· Parking garages

· Bridge decks

· Marine structures

· Slabs

· Roadways

In precast concrete (made in a manufacturing environment) it is more efficient, and results in cost and time savings.

· High early and higher ultimate compressive strengths

· Eliminates steam curing

· Savings on heating costs and rapid turnover of forms

In shotcrete applications, there is less material waste and greater efficiency of product use.

· High electrical resistivity and impermeability

· Significantly less rebound loss

· Mitigates reinforcing steel corrosion

· Improved bonding strength

· Thicker applications with each nozzle pass
