A concrete glue reducer

Abstract

The invention relates to a concrete glue reducer, which has the following formula components in terms of mass percentage: 1% to 3% sodium aminotrimethylene phosphonate, 2% to 5% resorcinol, 8% %~13% of the mixture of triisopropanolamine and N-methyldiethanolamine, the balance is water, the aminotrimethylene phosphonate sodium, resorcinol, triisopropanolamine and N-methyldiethanolamine The total amount of ethanolamine is 15%. As a novel concrete additive, the concrete glue reducer of the present invention has a three-dimensional molecular structure in part of the organic matter, and has strong micro-dispersion performance for cement. The glue reducer is added to the concrete to fully refine the cement particles while reducing the amount of cement, improve the initial fluidity of the concrete, and promote the hydration of ferrite, which is difficult to hydrate, to increase the hydration degree of cement minerals , so as to improve the early strength and effectively stimulate the later strength of cement and improve the compactness of concrete.

Description

technical field [0001] The invention relates to the technical field of chemical building materials, in particular to a concrete glue reducer. Background technique [0002] Cement is currently the most widely used building cementitious material in the world. With the continuous advancement of my country's urbanization process, the use of cement is increasing year by year. According to statistics, in 2013, my country's cement production reached 2 billion tons, accounting for about 40% of the world's cement. In addition, data show that for every 10,000 tons of cement produced, 15,500 tons of limestone, 12 million tons of coal, and 880,000 kilowatt-hours of electricity are consumed, and 10,000 tons of carbon dioxide and more than ten tons of sulfur dioxide and nitrogen oxide pollution are produced. It can be seen that the mass production and application of cement has brought greater pressure on resources and the environment. [0003] Due to the uneven level of technological d...

Problems solved by technology

[0003] Due to the uneven level of technological development in various regions, some civil mixing plants use a large amount of cement materials in order to seek better concrete workability, resulting in about 20% of cement being used as inert filling materials during the cement hydration process. Cement does not play its full role, which not only causes a waste of resources, but more importantly, has a serious negative impact on the durability of concrete

As a result, some civil projects had major quality problems just after they were built more than ten years ago, and they had to be dismantled, resulting in a lot of solid waste with nowhere to put them
