[0020] A preparation method of building cement, comprising the steps of:

[0021] S1. Weigh a certain amount of 85-100 parts of limestone, 20-30 parts of silica, 15-35 parts of granular river sand, 10-15 parts of bauxite, 18-25 parts of iron ore, 10-20 parts of copper slag, 20-25 parts of fly ash, 10-15 parts of clay and 10-20 parts of desulfurized gypsum are mixed, then added to a pulverizer for crushing, and then calcined at 600-900°C to obtain a mixture;

[0022] S2. Add a certain amount of water to the mixture obtained in step S1, then add 8-15 parts of stabilizer and 10-15 parts of grinding aid and stir for 15-20 minutes, let stand for 20-30 minutes and then stir for 10-15 minutes , to obtain a mixed solution;

[0023] S3, drying the mixed solution obtained in step S2 through a dryer to obtain cement;

[0024] S4, inspecting and packing the cement obtained in step S3 into storage.

Abstract

The invention discloses building cement and a preparation method thereof. The building cement is prepared from 85 to 100 parts of lime stone, 20 to 30 parts of silica, 15 to 35 parts of granular river sand, 10 to 15 parts of bauxite, 18 to 25 parts of iron ore, 10 to 20 parts of copper slag, 20 to 25 parts of fly ash, 10 to 15 parts of clay, 10 to 20 parts of flue gas desulfurization gypsum, 8 to 15 parts of stabilizer and 10 to 15 parts of grinding aid. According to the building cement and the preparation method thereof disclosed by the invention, by using the stabilizer, the integral stability of cement clinker is well improved; the grinding aid of the cement is low in mixing amount and good in enhancing effect, the cement performance and output per machine of the cement can be improved, and the production cost of the cement is reduced; according to the cement produced by the grinding aid, the ratio of clinker is low, the production cost is low, environmental pollution can be reduced, and mineral resources are saved; the building cement is low in price, is simple in production process and is suitable for scale production.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a construction cement and a preparation method thereof. Background technique [0002] The accelerated development of cities has brought a heavy burden to the environment. The consumption of cement is increasing, and there are many production plants. Slag has become a material in short supply. Cement plants often stop production due to the shortage of slag. In order to save energy, it is imperative to develop a cement produced from waste. [0003] The existing cement clinker, the cement clinker is made of raw materials with the following weight ratio: limestone 75-85; carbide slag 15-20; yellow sandstone 5-15; iron powder 2-5. Although this invention makes good use of calcium carbide slag, its stability and cohesive force are not enough; cement is an indispensable building material in human life and social production. called food". However, the cement production indus...
