Abstract

The invention belongs to the technical field of cement technology admixtures, and relates to a composite high-efficient liquid cement grinding aid which contains water solution with the following materials by weight percent: 10 to 20 percent of triethanolamine, 5 to 10 percent of glycol, 5 to 10 percent of tri-isopropanolamine, 5 to 10 percent of calcium lignosulphonate, 5 to 10 percent of molasses, and 5 to 10 percent of sodium silicate; and the water solution is subjected to magnetization treatment. The composite high-efficient liquid cement grinding aid has the following advantages: by the magnetization treatment, solid / liquid stable suspension durability is good, no separation or sediment phenomenon occurs after long-term storage, dosing amount is low, application range is wide, hourly output of a cement grinding mill can be improved by 15 to 20 percent, cement strength can be improved by 1 to 2MPa, 5 to 8 percent of clinker can be saved, and 5 to 8 percent of industrial residue can be additionally dosed.

Description

technical field

[0001] The invention relates to a composite high-efficiency liquid cement grinding aid, which belongs to the technical field of cement process admixtures. A small amount of grinding aid is added in the grinding process of cement production, which can improve grinding efficiency and cement performance. Background technique

[0002] At present, the liquid cement grinding aids commonly used in the cement production industry mainly have deficiencies and unscientific aspects in the following technical aspects: such as long-term storage to produce precipitation, poor persistence of solid-liquid stable suspension, poor grinding aid effect, and narrow application range. The effect of improving cement performance is poor, containing NH 3 and other harmful ingredients, the use cost is high. Contents of the invention

[0003] In order to overcome the deficiencies in the above technical aspects, the present invention provides a high-efficiency composite liquid cement ...
