Basalt is a good raw material for the production of "cast stone". "cast 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 used as a "lubricant" in an advanced process of cast steel to extend the life of the cast film. 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 reduce the weight of concrete, but it is still strong, and it is soundproof and heat-insulated. 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.
Basalt has excellent compression and flexural properties, good wear resistance and low water absorption. It is also a very good building decoration material. It can be widely used in indoor and outdoor decoration, and it is mainly used as outdoor stone. Its color is natural. It is well coordinated with the surrounding landscape and is ideal for outdoor landscape construction, especially for the best choice of floor tiles. However, as mentioned above, basalt is easy to form hexagonal columnar joints, and it is brittle, so the stone blocks are generally small, lacking large materials, and it is not easy to produce large-size plates.
Among them, multi-porous basalt, also known as pumice stone, has many pores and hard texture. It can be placed in concrete, which can reduce the weight of concrete. It is not only durable, but also 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. It can also be used as filters, dryers, catalysts, etc. in the industry. It is also widely used in garden landscapes, mainly used as rockery, bonsai, etc. It is also used in home decoration.
The use of basalt is very extensive, and its application is not limited to the construction industry. For example, basalt is a good raw material for the production of "cast stone". After melting casting, crystallization treatment, annealing and other processes, alloy steel can be formed to be hard and wear-resistant. A new type of material that is resistant to corrosion by lead and rubber; basalt can also function as a "lubricant" in an advanced process of cast steel, which can be used for long film life; and basalt can also be made into glass. Basalt glass cloth is more resistant to alkali than ordinary glass cloth and has good high temperature resistance. [2]
Basalt is the best material for repairing stone used in highways, railways and airport runways. It has strong pressure resistance, low crushing value, strong corrosion resistance, asphalt adhesion basalt, basalt has wear resistance and less draft. It has the advantages of poor electrical conductivity, strong pressure resistance, low crushing value, strong corrosion resistance and asphalt adhesion. It is internationally recognized and is the best cornerstone for the development of railway transportation and road transportation.
Some artists, according to the characteristics of pumice porous and wrinkled, leaking. It is used to build rockeries in gardens or to create small and bonsai.
It is a compact or foam-like structure that is solidified by the volcanic eruption of the 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 degrees Celsius. Because of 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 greatly accelerated. It carries a lot of water vapor and bubbles during the flow, and after cooling, it forms various variograms.
