Multi-vesicular basalt (pumice), because it is more pores, but also very hard, therefore, it would be mixed in concrete, you can reduce the weight of the concrete, but still strong, while there are sound and heat insulation characteristics, high-rise building good lightweight oncrete aggregate.Pumice is a very good abrasive material that is used to grind metal, Grinding stones; can be done in the industry filter, dryers, catalysts.
According to the effective data analysis, is to determine the characteristics of basalt his multi-favored major factor. Basalt, is the production of “cast stone” a good raw material.It is the melting of basalt after casting, the crystallization process, annealing is made of the material. It is hard and wear-resistant than steel, corrosion resistant than lead and rubber.
Basalt is also one kind of advanced casting process, act as a “lubricant” role, cast film can prolong life. At the same time, also can be pumped into the basalt glass, glass fiber cloth than strong alkali resistance, high temperature performance.
Furthermore basalts repair roads, railways, airport runways used by the best stone materials with compression and strong, crushing value is low, corrosion resistance, adhesion of asphalt basalt stone, basalt stone with wear, less draft , poor conductivity, compression resistance, crushing value is low, corrosion resistance, adhesion of asphalt, etc., and is internationally recognized,is the development of rail transport and road transport best cornerstone.
