Cement grinding additive

Abstract

The invention discloses a cement grinding additive. The cement grinding additive comprises the following components in parts by weight: 10-25 parts of anhydrous sodium sulphate, 2-5 parts of polymeric alkylol amine, 1-3 parts of calcium formate, 0.5-2.3 parts of aluminum sulfate, 8-12 parts of ethylparaben, 5-10 parts of waste sugar residue, 2-6 parts of pulverized fuel ash, 2-8 parts of polyethylene glycol, 1-4 parts of an initiator and 20-30 parts of water. The cement grinding additive is high in stability and low in cost, and can be used for effectively increasing the utilization rate of the energy in the cement grinding process.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a cement grinding aid. Background technique [0002] Cement grinding is the process link with the highest energy consumption in the cement production process. During the grinding process, it often causes problems such as a decrease in cement powder selection efficiency and a decrease in grinding efficiency. In order to improve the grinding and grinding conditions, it is generally necessary to add cement grinding aids. However, the commonly used cement grinding aids have problems such as high manufacturing cost and large demand. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cement grinding aid, which solves the problems of high cost and large demand of existing grinding aids. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present inven...
