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.
1).Appearance is as grey&white off.
2).High electrical resistivity
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
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
