Problems solved by technology

[0003] However, some municipal projects and infrastructure projects, such as railways, highways and other facilities, have higher standards for the performance of cement because the quality of the project is related to public safety. It is difficult for the cement sold on the market to meet this requirement. , and the price is much higher than ordinary cement

Abstract

The invention discloses a cement reinforcer which comprises the following components in parts by weight: 8-18 parts of zeolite powder, 15-22 parts of precipitated barium sulfate, 8-12 parts of talcum powder, 30-38 parts of diatomite powder, 13-21 parts of borax, 9-14 parts of acrylamide, 9-21 parts of calcium lignosulphonate, 4-7 parts of sodium acetate, 9-18 parts of ethylene glycol, 2-4 parts of urea, and 48-62 parts of water. The relative density of the cement reinforcer disclosed by the invention is 1.12-1.21, which is much smaller than the density of cement paste, so that an anti-fluid-channeling effect can be achieved on the premise of not changing the density of cement paste; according to the invention, composite cement concrete has the functions of heat insulation, heat preservation, insulation, resistance, and the like, so that artificial maintenance can be omitted; because after the reinforcer is added, the reinforcer is expanded and produces a dynamic reverse reaction to the solidification of cement, duo to the expansion operation, the strength of cement and the cementing strength of cement with other media are significantly improved, and cement also can be saved by 28-36%; and according to the invention, the heat produced in the process of solidification caused by a chemical reaction between cement and water is reduced by about 50%, thereby achieving an anti-crack effect.

Description

technical field [0001] The invention relates to a cement additive, in particular to a cement reinforcing agent. Background technique [0002] Looking at the overall situation of the national cement industry, the national cement output in 2010 was 1.868 billion tons, a year-on-year increase of 15.5%. In 2011, it is estimated that about 90 million tons of new production capacity will be added, and about 100 million tons of outdated production capacity will be eliminated. From the perspective of demand, in 2011, the "4 trillion stimulus policy" has greatly weakened the promotion effect on cement, but most of its projects are still under construction, still supporting the demand for cement, while water conservancy, high-speed rail and other construction The rise of cement has also ensured the demand for cement to a certain extent. [0003] However, some municipal projects and infrastructure projects, such as railways, highways and other facilities, have higher standards for th...
