Abstract

The invention relates to a composite industrial residue mineralizer cement clinker and a preparation method thereof. The mineralizer doped into a cement green stock is between 5 and 20 percent by weight, and the cement clinker is characterized in that raw materials consist of 50 to 80 percent of metallic slag and 20 to 50 percent of inorganic non-metallic slag, wherein the metallic slag comprises the following components in portion by weight: 25 to 45 portions of steel slag, 15 to 40 portions of barium slag, 15 to 35 portions of chromium slag, 5 to 30 portions of zinc slag, 5 to 15 portions of copper slag, and 5 to 10 portions of tungsten slag; and the inorganic non-metallic slag comprises the following components in portion by weight: 25 to 45 portions of sulfuric acid slag; 25 to 40 portions of iron purite slag, 5 to 15 portions of phosphogypsum slag, 5 to 15 portions of coal slag, 5 to 10 portions of coal gangue slag, and 5 to 10 portions of rare-earth slag. The preparation method comprises the following steps: (1) mixing the metallic slag and grinding the metallic slag into fine powder; (2) mixing the inorganic non-metallic slag and grinding the inorganic non-metallic slag into fine powder; (3) mixing the metallic slag with the inorganic non-metallic slag evenly according to weight proportion; (4) activating the fine powder; and (5) blending the clinker fine powder into cement green stock.

Description

technical field [0001] The invention belongs to building materials and provides a cement clinker prepared by using a compound industrial waste residue mineralizer and a method for compounding the industrial waste residue mineralizer cement clinker. technical background [0002] In the cement production process, an appropriate amount of mineralizer should be added to the cement raw meal, and then calcined to make cement clinker. At present, most cement manufacturers use traditional fluorine-sulfur mineralizers, mainly composed of fluorite and gypsum. However, this mineralizer has outstanding problems, mainly as follows: due to limited fluorite resources and high prices, the cost of cement production is high; Pollution and corrosion of equipment. In addition, if used improperly, such mineralizers are likely to cause abnormal setting time of cement and affect the quality of cement. [0003] As we all know, adding some industrial waste slag to cement raw meal can improve the ...
