Cement reinforcing modifier

Abstract

The invention provides a cement reinforcing modifier. The mixing amount of cement is 0.1% to 0.5% by weight of the cement. The cement reinforcing modifier is prepared from the following components inpercentage by weight: 1% to 15% of liquid diethanol monoisopropanolamine or liquid triethanolamine, 1% to 10% of sodium gluconate or white sugar or brown sugar, 0.7% to 10% of sodium thiosulfate or sodium sulfate, 0. 3% to 5% of acetic acid, and 60% to 95% of carrier. The cement reinforcing modifier provided by the invention is added into the cement from a cement production ball mill or a verticalgrinding tail. The cement reinforcing modifier provided by the invention has the advantages of improving the strength of the cement, reducing the amount of clinker by 2% to 4%, reducing the cement producing cost, and reducing the water demand of standard consistency of cement by 2 to 4 ml. The cement reinforcing modifier provided by the invention is mixed with a concrete water reducing agent without the formation of precipitates, which can reduce the gradual loss; the ash and sand flying can be controlled by the cement reinforcing modifier when the floor is produced by the cement, and the surface hardness of the cement is improved.

Description

technical field [0001] The invention relates to the technical field of cement chemical industry, in particular to a cement reinforcing modifier. Background technique [0002] Cement production is made by grinding cement clinker mixed with retarder gypsum and mixed materials. In the production process, it is often necessary to add grinding aids to improve grinding efficiency and increase cement strength. The strength of cement has limitations, and the strength of cement has not been maximized, resulting in large clinker consumption and high production costs; moreover, the produced cement often requires more water due to the water absorption of the mixture, and has poor workability during use. It is convenient for construction. In addition, due to the high proportion of mixed materials in the production process to reduce costs, the cement is prone to bleeding, and the floor is prone to ash.

[0002] Cement production is made by grinding cement clinker mixed with retarder gypsum and mixed materials. In the production process, it is often necessary to add grinding aids to improve grinding efficiency and increase cement strength. The strength of cement has limitations, and the strength of cement has not been maximized, resulting in large clinker consumption and high production costs; moreover, the produced cement often requires more water due to the water absorption of the mixture, and has poor workability during use. Convenient construction

In addition, due to the high proportion of mixed materials in the production process to reduce costs, the cement is easy to bleed, and the floor is easy to dust

[0003] Due to the different types of grinding aid chemical materials used by various manufacturers, the produced cement of grade 42.5 or above often conflicts with the water reducing agent when it is formulated into concrete, resulting in a large loss over time, which brings great harm to concrete transportation and construction sites. come to trouble
