Problems solved by technology

Cement slaking is the stage that consumes the most heat energy in cement production. The mineralizers such as fluorite added in the existing production are mainly to reduce the sintering temperature, reduce heat consumption, and improve the quality of clinker. However, the fluorine in fluorite is easy to cause environmental pollution. Pollution, and has limited effect on accelerating the formation of clinker minerals and shortening the calcination time

Embodiment 1

[0010] Mix potassium permanganate, sodium carbonate, manganese carbonate, dicobalt trioxide and sodium borate in a mass ratio of 1:0.5:0.5:0.5:0.03, then add 0.7wt% to the cement raw material, calcined and matured, Portland cement clinker is obtained.

Embodiment 2

[0012] Mix potassium permanganate, sodium carbonate, manganese carbonate, dicobalt trioxide and sodium borate in a mass ratio of 1:1.5:1:0.7:0.02, then add 0.5wt% to the cement raw material, calcinate and mature, Portland cement clinker is obtained.

Embodiment 3

[0014] Potassium permanganate, sodium carbonate, manganese carbonate, cobalt trioxide and sodium borate are mixed evenly in a mass ratio of 1:1:0.2:1:0.03, and then added to cement raw materials in an amount of 1 wt%, calcined and matured to obtain Portland cement clinker.

[0015] Under the same conditions, compared with the addition of fluorite, the cement curing catalyst of the present invention can reduce the curing (calcination) time by 11-15%.

Abstract

The invention discloses a cement curing catalyst, which comprises potassium permanganate, sodium carbonate, manganese carbonate, dicobalt trioxide and sodium borate, wherein potassium permanganate, sodium carbonate, manganese carbonate, dicobalt The mass ratio to sodium borate is 1: (0.5-1.5): (0.2-1): (0.5-1): (0.02-0.03). Compared with the conventional addition of fluorite, the cement slaking catalyst of the invention can reduce the slaking (calcination) time by 11-15%, and will not pollute the environment.

Description

technical field [0001] The invention belongs to the field of cement admixtures and relates to a cement curing catalyst. Background technique [0002] The aging process of Portland cement raw materials is also a process of carbonate decomposition and solid phase reaction of clay and oxides produced by decomposition. Cement slaking is the stage that consumes the most heat energy in cement production. Mineralizers such as fluorite are added in the existing production mainly to reduce the sintering temperature, reduce heat consumption, and improve the quality of clinker. However, the fluorine in fluorite is easy to cause environmental pollution. Pollution, and has limited effect on accelerating the formation of clinker minerals and shortening the calcination time. Contents of the invention [0003] The technical problem to be solved by the invention is to overcome the existing defects and provide a cement curing catalyst. [0004] In order to solve the problems of the techno...
