Iron grit

Main ingredient is iron oxide, in fact, widely used, the effect is satisfactory. It is not only wear, compression, impact resistance, also has a moisture-proof, acid corrosion resistance, high temperature and other properties. The sand is the preferred material for blasting area is an ideal building materials new wear-resistant material. The product is used in the construction made ​​of iron just wear layer of concrete sand or iron sand mortar just wear layer, the compressive strength, splitting tensile strength, friction coefficient, etc. are better than iron Molybdenum tube wear layer, easy to iron rot rust off phenomenon occurred, and iron sand just is not true, just sand iron compared with diabase, not only low cost, simple construction, its impact strength and brittleness values ​​in excess of diabase about twice. So three decades of China's coal, electric power, chemical and metallurgical and other industrial infrastructure projects are widely used in iron wear layer of sand to make concrete or mortar just wear layer.
