Micro silicon powder is the material with broad application and bright future in world's high-tech fields. It can be widely used in chemical, metallurgical and other industries. Using in the cement and concrete to improve the performance of cement or concrete, preparing with a high, high strength, wear resistance, erosion, corrosion, anti-penetration, frost, early strength special cement concrete or composite to suit oilfield cementing, marine oil drilling platforms, harbor terminals, railway bridges highways, airport runways, tunnels and urban high-rise building projects such as special requirements; for rubber can improve the rubber elongation, tensile strength, tear resistance; for refractory ceramic products, effectively improve the strength of the product durability.
Micro silicon powder concrete applying in water conservancy and hydropower projects can improve the ability of anti-erosion projects in the world with more traditional anti-abrasive material such as epoxy polymer mortar, anti-abrasion ability of these materials is good, but because it itself several times in the linear expansion coefficient plain concrete basement, concrete temperature and substrate fit well, easy to crack under natural climatic conditions off, and the construction of complex, toxic, expensive, not in large scale. The use of silica fume concrete, about double the capacity of scour erosion, anti-48m / s velocity-level resistance to abrasion capacity more than 3 times.
On the use of hydraulic concrete, micro silicon powder can improve the crack resistance of hydraulic engineering concrete cracks. It has become a major issue with common concern. Cause cracks in the heat of hydration heat as the material itself, such as concrete mixed with fly ash, although you can reduce the temperature of heating, but the early strength is relatively low, so that the amount of fly ash is limited.
Micro silicon powder concrete can improve the anti-permeability properties of salt corrosion and protect the bars. Underwater engineering because chloride ions penetrate, causing rapid corrosion of steel, boron powder concrete delamination, short life, destructive serious. Underwater concrete pouring commonly used catheter, due to cement loss, it can not be a good bond with the primary and lower part of the intensity of contact with water. Underwater concrete mixed with micro silicon powder, these issues can have significant improvement.
Micro silicon powder concrete is used in repairing the traffic problems with strong wear-resistant properties. Pouring concrete with ordinary road need 28 days to realize the normal traffic, usually early-strength concrete need three days to realize the opening.The surface damage of concrete road is inevitable. Repairing with conventional methods, it often results in broken traffic, leading to serious economic losses. The use of early strength and wear characteristics of a micro-silica fume concrete, the practical application of the results are quite satisfactory. Airport runway requires more than 80MPa concrete with good wear resistance. Micro silicon powder can also realize its great function. Source:http://www.mhcmp.com
