玄武岩资料（Basalt data） Due to the small viscosity of basalt melts, condensation is hard and compact. It can cast stone (cast stone /view/309116.htm) raw materials. The cast stone is basalt after melting and casting, annealing and crystallization process of materials. The basalt is the production of good raw stone. Stone is the basalt through melting casting and crystallization processes, and annealing the material. It is harder and more wear-resistant than alloy steel and is more resistant to corrosion than lead or rubber. Basalt is also a lubricant in the advanced process of casting steel. It can extend the service life of casting film. At the same time, can also be pumped into basalt glass fiber, glass fiber cloth than alkali resistance, high temperature resistant performance is good. Multi vesicular basalt, porosity content 50% (Fu Shi), because of its porosity, but also quite hard, therefore, it will be mixed in concrete, concrete can be made lighter, but still very strong, and sound insulation, insulation and other features, is a good aggregate of lightweight concrete in high-rise building. Pumice is a very good material for grinding metals and grinding stones. It can also be used as filters, dryers, catalysts and so on in industry. After the basalt sand making machine is broken or broken stone to repair the highway, railway, airport runway by use of the best materials of stone, with strong resistance, low crushing value and strong corrosion resistance and adhesiveness of asphalt basalt, basalt stone has wear-resisting, eat less water, poor conductive property, strong resistance, crushing the advantages of low value, strong corrosion resistance, adhesiveness of asphalt, and is internationally recognized, is the development of railway transportation and road transportation in the best basis. Many high-tech composites are also used in Xuan Wuyan The volume density of basalt is 2.8 ~ 3.3g/cm3. The compressive strength of compact is very large, which can be as high as
