Abstract

The invention discloses a concrete synergist and a preparation method thereof. The raw materials are composed of the following components by weight: 20-40 parts by weight of alcohol amine, 6-12 parts by weight of alcohol, 5-10 parts by weight of inorganic salt, phosphine 4-12 parts by weight of acid, 0.05-0.3 parts by weight of air-entraining agent, 0.01-0.05 parts by weight of silicone defoamer, 0.01-0.05 parts by weight of foam stabilizer and 35-60 parts by weight of water, wherein the alcohol amine is monoethanol One or both of diisopropanolamine, aminoethylethanolamine or N,N‑diethylpropanolamine, the alcohol is at least one of diethylene glycol and 1,5‑pentanediol, inorganic salt Potassium pyrophosphate or sodium pyrophosphate. The concrete synergist of the invention has the advantages of non-toxic finished products, uniform dispersion, simple process, no pollution, low energy consumption, easy industrial production, and can effectively improve the workability and slump retention of concrete and increase the strength of concrete. By reducing the amount of cement, the hydration reaction efficiency of cement in concrete can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a concrete synergist and a preparation method thereof. Background technique [0002] Concrete is one of the most used building materials at present, so far, there is no foreseeable material that can replace the application of concrete. However, research data on the degree of cement hydration at home and abroad show that under normal circumstances, about 20-30% of the cement in concrete does not participate in the hydration reaction and does not function normally, which is the biggest waste of cost in concrete applications. Therefore, how to make full use of cement resources has extraordinary significance for realizing energy saving, emission reduction and sustainable development. [0003] Synergist is a new type of concrete admixture that has been promoted and used in the construction market in recent years. In the case of ensuring the comprehensive perfo...
