Cement reinforcing agent

Abstract

The present invention discloses a cement reinforcer. 0.5-1.5 part per thousand of cement intensifier and modest plaster are added to cement clinker to be ball-milled to crank out the cement. The cement reinforcer is composed of triethanolamine, ethylene glycol, acetic acid sodium or anhydrous sodium acetate, urea, calcium chloride and calcium lignosulfonate, wherein, the mass percentage of the components is: triethanolamine: 5-25 percent; ethylene glycol: 5-25 percent, acetic acid sodium or anhydrous sodium acetate 1-10percent; urea: 10-30 percent; calcium chloride: 5-30 percent; calcium lignosulfonate: 3-20 percent. Under the condition of equivalent clinker, the application of the cement reinforcer provided by the invention can help improve 3-10 MPa of the cement compressive strength and reduce 10-15 percent of the clinker amount (namely, the dosage of the re-introduction of cheap mixed materials) in the original cement formula, so as to save 6-15 yuan on the cement cost per ton. Moreover, the invention can make full use of industrial mixed waste materials so as to save the mineral resources, reduce the cement costs and improve the ecological environment. The cement intensifier is easy to use and simple to be operated, and need not change the existing cement production process.

Description

technical field [0001] The present invention relates to cement, and in particular to auxiliary additives for the manufacture of cement. Background technique [0002] As we all know, cement is one of the main products of building cementitious materials. Cement is silicate clinker made by mixing limestone, coal, iron powder and clay and other mineral raw materials, and then adding gypsum to the clinker and grinding finely made. With the rapid development of my country's economy, the amount of cement is increasing exponentially. Therefore, the consumption of mineral raw materials such as limestone, coal, iron powder and clay is increasing day by day, and the mineral resources are continuously decreasing. At present, under the premise of ensuring the strength of cement, cement manufacturers appropriately mix some mixed materials (industrial waste) through technical means, so as to achieve the purpose of saving mineral resources, reducing cement costs and protecting the environm...

However, limited by the requirements of the cement strength standard, the amount of the above-mentioned mixture should generally not exceed 20%, otherwise, the compressive strength of the cement will be significantly reduced
