Abstract

The invention discloses a cement clinker. The cement clinker is prepared from the following components in parts by weight: 95-110 parts of limestone, 5-8 parts of phosphorus slag, 3-5 parts of copperslag, 1-3 parts of fly ash and 0.1-0.3 part of a stabilizer. According to the cement clinker, when industrial waste residues are adopted to replace natural sandstone and clay as ingredients, the fluidity of slurry can be effectively improved, the water content of the slurry entering a kiln is reduced, a small amount of phosphorus and fluorine can be introduced into the phosphorus residues, the content of C3A is obviously reduced due to the existence of the fluorine to enable Al2O3 to be more subjected to solid solution in ferrite-aluminate to form C6AF2, CaF2 and C3S in a liquid phase are subjected to solid solution to form a C11S3CaF2 annulus to wrap alite crystals to enable the early hydration speed of C3S is slowed down, so that the setting performance and strength performance of the cement clinker are improved, the overall performance of the cement clinker is obviously improved, in addition, the industrial waste residues are adopted, so that wastes are changed into valuables, and the production costs of enterprises are reduced.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a cement clinker. Background technique [0002] Cement clinker is a semi-finished product obtained by using limestone and clay as the main raw materials, which are prepared into raw meal in an appropriate proportion, burned until part or all of it is melted, and cooled. [0003] Cement is a powdery hydraulic inorganic gelling material. After adding water and stirring, it becomes a slurry, which can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. [0004] In the prior art, natural sandstone and clay are often used as ingredients in the production of cement clinker, but the price of natural sandstone and clay is relatively expensive, which will increase the production cost of the enterprise. Contents of the invention [0005] The purpose of the invention is to solve the problems in the prior art, and pr...
