Problems solved by technology

Cement clinker is an important part of cement. The material properties of cement clinker determine the material properties of cement. However, cement clinker in the prior art usually releases a lot of heat during the cement hydration process, which leads to early shrinkage of cement and large The internal temperature rise of bulk cement causes cracks, and alkali-aggregate reaction is prone to occur

Abstract

The invention discloses reinforced cement prepared from an aluminum ash regulator, and belongs to the technical field of cement materials. The Portland cement comprises Portland cement clinker and auxiliary materials, and the mass ratio of the Portland cement clinker to the auxiliary materials is 1: 0.3. The Portland cement clinker is prepared from the following raw materials in parts by weight: 200 to 250 parts of clay, 120 to 160 parts of limestone, 30 to 60 parts of iron ore, 15 to 25 parts of an aluminum ash regulator and 10 to 30 parts of a reinforcing mixed material, and the reinforcing mixed material is a mixture of pyrite slag, copper slag and hydroxyethyl methyl cellulose ether. The mass ratio of the pyrite slag to the copper slag to the hydroxyethyl methyl cellulose ether is 4: 5: 17; the auxiliary material is gypsum powder. Grinding into a raw material by using a mill, calcining in a kiln, and cooling to obtain a clinker; then calcining at high temperature to obtain a clinker; and finally, mixing the clinker, the gypsum powder and the reinforced admixture, and grinding for the second time. The reinforced cement disclosed by the invention has relatively good comprehensive performance.

Description

technical field [0001] The invention belongs to the technical field of cement materials, and in particular relates to a reinforced cement prepared by using an aluminum ash regulator. Background technique [0002] Cement is a cementitious material made by mixing and grinding limestone, silica-alumina materials, iron materials, etc. in proportion, then calcining clinker at high temperature, adding mixed materials, retarders and other materials to the clinker, and grinding to a certain fineness. . With the continuous development of the construction industry, the demand for cement is also increasing. Cement clinker is an important part of cement. The material properties of cement clinker determine the material properties of cement. However, cement clinker in the prior art usually releases a lot of heat during the cement hydration process, which leads to early shrinkage of cement and large The internal temperature rise of bulk cement causes cracks, and alkali-aggregate reaction...
