Abstract

The invention relates to a concrete gel reducing agent which comprises the following formula components in percentage by weight: 1%-3% of phosphonic acid ramifications A, 2%-5% of hydroxy aromatic compounds B, 8%-13% of alkylamine C and the balance of water, wherein the total amount of the phosphonic acid ramifications A, the hydroxy aromatic compounds B and the alkylamine C is 15%. A part of organic substances contained in the concrete gel reducing agent used as a novel concrete additive have molecular structures with three-dimensional spaces and have higher micro dispersion property on cement. If the gel reducing agent is doped into concrete, cement particles are sufficiently refined under the condition that the usage amount of the cement is reduced, the initial flowing property of the concrete is improved, and the hydration degree of a cement mineral is enhanced by promoting the hydration of ferrite which is more difficult to hydrate, so that the early strength is enhanced, the later strength of the cement is effectively excited and the compactness of the concrete is enhanced.

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...
