Building materials are all kinds of materials used in building engineering. There are a wide variety of building materials, which can be roughly divided into:
(1) inorganic materials, including metal materials (including ferrous metal materials and non-ferrous metal materials) and non-metallic materials (such as natural stone, soil-burning products, cement, concrete and silicate products, etc.).
(2) organic materials, including plant materials, synthetic polymer materials (including plastics, coatings, adhesives) and asphalt materials.
(3) composite materials, including asphalt concrete, polymer concrete, etc., generally composed of inorganic non-metallic materials and organic materials.
Coal ash is composed of oxides and salts of silicon, aluminum, iron, titanium, calcium, magnesium, sulfur, potassium, sodium and other elements.
Refractory not less than 1580℃ of the first class of inorganic non-metallic materials, is widely used in iron and steel, non-ferrous metals, glass, cement, ceramics, petrochemical, machinery, boiler, light industry, electric power, military and so on.
Glass is a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda, etc.) for the main raw materials, add a few auxiliary raw materials to do. Its main components are silicon dioxide and other oxides.
Analyze and test raw material, clinker, cement, clay, limestone, iron powder, gypsum, ash, sandstone, slag, coal and other oxides in cement industry.
