What's the difference between lime and cement? What's the main ingredient? What's the use?
The natural rock, which is mainly composed of calcium carbonate, is calcined at an appropriate temperature to remove carbon dioxide from decomposition. The product obtained with calcium oxide (CaO) as the main component is lime, also known as quicklime. 2. the main component of cement: the main component is silicate.
There are many kinds of cement, and their composition is different.The name, main components of ordinary cement chemical formula: three calcium silicate, calcium silicate, calcium aluminate two three: 3CaO - SiO2,2CaO - SiO2,3CaO - Al2O3, gypsum and other ingredients. The old label and different grade cement cement have different uses
A rigid inorganic gelling material with calcium oxide as its main component. Lime is made from limestone, dolomite, chalk and shell with high content of calcium carbonate and calcined at 900~1100 DEG C. Lime is one of the earliest cementitious materials used in human life. In the eighth Century BC, the ancient Greeks were already used for construction, and China began to use lime in the seventh Century bc. Lime is still a widely used building material today. Lime has quicklime and slaked lime (ie slaked lime), according to its Magnesium Oxide content (within 5%), and can be divided into calcium lime and magnesium lime. Because of its wide distribution of raw materials, simple production process and low cost, it is widely used in civil engineering. Any natural rock consisting mainly of calcium carbonate, such as limestone, chalk, dolomitic limestone, etc., can be used to produce lime.
