What is the use of basalt?
Basalt is a dense or foamy structure of rock that is solidified by the volcanic eruption of magma. It belongs to magmatic rock (also called igneous rock) in the geological rock classification. The magma temperature from the volcanic eruption is as high as 1200 mils. Due to the certain viscosity, when the terrain is gentle, the magma flows very slowly, only a few meters away per minute; when it encounters a steep slope, the speed is greatlyChina basalt products Suppliers accelerated. It carries a lot of water vapor and bubbles during the flow, and after cooling, it forms various variograms. Jingbo Lake has a waterfall-like and wavy shape; Yingge Ridge has a round-headed shape and a pagoda-like shape; between Bohai Town and Shalan Township, it is a giant scorpion and a lava tunnel. Here, the geology and geomorphology are new and different in form and rich in variety.
The color of basalt is mostly black, dark brown or dark green. Because of its dense texture, its specific gravity is heavier than ordinary granite, limestone, sandstone and shale. However, some basalts have a lot of stomata, their weight is reduced, and they can even float in the water. Therefore, the light basalt of this porous body is called "pumice stone". Some artists, according to the characteristics of pumice porous and wrinkled, leaking. Used to build rockeries in gardens, or to create small and bonsai.
According to the analysis of geological scientists, the main components of basalt are silica, alumina, iron oxide, calcium oxide, magnesium oxide (and a small amount of potassium oxide, sodium oxide), of which silica content is the most, accounting for about 100. It is about forty-five to fifty.
Basalt is a good raw material for the production of "cast stone". "Casting stone" is a material obtained by melting, casting, and annealing basalt. It is harder and more wear resistant than alloy steel and more resistant to corrosion than lead and rubber. Basalt is also a "lubricant" in the advanced technology of cast steel, which can be used for long casting life. At the same time, basalt can also be drawn into glass filaments, which is more alkaline than ordinary glass cloth and has good high temperature resistance.
Multi-porous basalt (pumice), because it has many stomata and is quite hard, so it can be used in concrete to make the weight of the concrete lighter, but it is still strong, and it has the characteristics of sound insulation and heat insulation. It is a high-rise building. Good aggregate of lightweight concrete. Pumice is also a very good abrasive material, which can be used to grind metal and grindstone; in industry, it can also be used as filter, dryer and catalyst.
