What is the use of basalt?
Multi-stomatal basalt (pumice), because it is more stomatal, and quite hard, so it will be mixed with concrete, can reduce the weight of concrete, but still very strong, while noise, heat insulation and other characteristics, is high-rise building Light concrete is a good aggregate. Pumice is still a good grinding material, can be used to mill metal, grinding stone; in the industry can do filters, dryers, catalysts and so on.
Basalt is a good raw material for the production of "cast stone." "Cast stone" is a material that is developed by melt casting, crystallization, and annealing. It is harder and wear resistant than alloy steel and is resistant to corrosion than lead and rubber. In a kind of advanced technology of cast steel, it plays the role of "lubricant", can be a long casting life. At the same time, basalt can also be drawn into glass fiber, than the general glass cloth anti-alkali strong, high temperature performance.
According to geological scientists analysis and identification, the main components of basalt is silica, alumina, iron oxide, calcium oxide, magnesium oxide (and a small amount of potassium oxide, sodium oxide), of which the largest silica content, Four to fifty to fifty.
Basalts are mostly black, dark brown or dark green, and because of their dense texture, the proportion of granite, limestone, sandstone and shale is heavy, but some basalts are much more , Even in the water can float.Therefore, this kind of porous body light basalt, called "pumice." Some artists, according to pumice porous and wrinkled, leak characteristics. Used to build the garden of rockery, or carved into small and exquisite Bonsai.
A rock of a dense or foamy structure that is solidified by volcanic eruptions from volcanic eruptions, which belongs to magmatic rocks (also called igneous rocks) in the classification of geology rocks. The magma temperature of volcanic eruptions Up to 1200 degrees Celsius, due to a certain degree of viscosity, in the gentle terrain, the magma flow is very slow, only a few meters per minute flow; encountered steep slope, the speed will be greatly accelerated in the flow process, carrying a lot of water Steam and air bubbles, after cooling, they formed a variety of variations in the shape of the temple of Hubei waterfall-like, wavy; Yingge Ling area with round bread-like, pagoda-like; Bohai Town and Shalan Township, is a giant Python and lava tunnel, etc. Geology, geomorphic structure of the new Ying, different shapes, colorful.
