Micro-silica fume in the building materials industry and sales

Micro-silica fume is at home and abroad in the field of high and new technology has broad application prospects for the fine material can be widely used in chemical industry, metallurgical industry. For cement or concrete to improve the performance of concrete or cement, prepared with ultra-high, strong, wear-resistant, resistant to erosion, corrosion-resistant, anti-penetration, antifreeze, the early strength of concrete or special cement compound to meet the oil - Well, marine oil drilling platform, harbor terminals, railway bridges highways, airport runways, tunnels and urban high-rise building projects, such as the special requirements; rubber can be used to improve the extension of rubber, tear and tensile strength ; For ceramics and refractories, effective products to improve the strength and durability.
     1. Micro-silica fume concrete used in water conservancy and hydropower project, the project can improve the ability of anti-erosion at home and abroad traditional anti-abrasion material to make more use of polymer materials such as epoxy mortar, anti-erosion ability of such materials is a good one, but because of its own Linear expansion coefficient several times in the basement of ordinary concrete, concrete basement and adapt to the temperature is not good, in the natural climatic conditions cracking off easily, and construction of the complex, toxic, costly and can not promote the use of a large area. The use of micro-silica fume concrete, abrasive impact the ability to double about anti-48m / s velocity-class anti-erosion ability to raise more than 3 times.

     2. Micro-silica fume concrete in the water, the project can improve the crack resistance of hydraulic concrete cracks, has become a major issue of general concern. Cracks in the material itself due to hydration heat of warming, such as the incorporation of fly ash in concrete, although lower-temperature electric heating, but the early strength is relatively low, so that the limited amount of fly ash.

     3. Micro-silica fume concrete can improve the performance and the infiltration of anti-corrosion properties of salt to protect the steel.

     Underwater engineering due to infiltration of chloride ions in concrete, causing rapid corrosion of reinforced concrete delamination,  short life expectancy, a serious destructive. Underwater concrete pouring generally catheterization, as the loss of cement so that it can not bond with the grass-roots level, and to reduce contact with water in some of the strength. The introduction of concrete under water in the micro-silica fume, these problems could have significantly improved.

     4. Micro-silica fume concrete road traffic in the road repair, is extremely wear-resistant properties
