Anti-freezing concrete water reducer

Abstract

The invention belongs to the technical field of concrete admixtures, in particular to an antifreeze concrete water-reducer, which is made of the following raw materials in parts by weight: 35-60 parts of polycarboxylate water-reducer, 1-2.2 parts of tea saponin, alkyl 0.5-1.5 parts of glucoside, 0.5-2.8 parts of sodium carboxymethylcellulose, 0.3-0.9 parts of borax, 0.2-0.8 parts of hydroxyethylidene diphosphonic acid, 10-25 parts of water. The antifreeze concrete water reducer of the present invention not only has good water reducing effect, but also has good antifreeze performance and can strengthen the strength of concrete.

Description

technical field [0001] The invention belongs to the technical field of concrete admixtures, in particular to an antifreeze concrete water reducer. Background technique [0002] Polycarboxylate superplasticizer is the third-generation superplasticizer with excellent comprehensive performance. It has been produced and applied in Japan, Germany, the United States and other developed countries since the late 1980s. It has many advantages such as high water reducing rate, small loss of concrete slump over time, low dosage, great contribution to concrete strength, and good environmental protection. From high-speed railways to urban commercial concrete mixing stations, many domestic application companies have begun to choose polymer Carboxylic acid superplasticizer is an essential fifth component of concrete. As a new type of material, concrete water reducer can not only improve the level of construction technology, improve the performance of concrete, but also save a lot of cemen...

Problems solved by technology

[0003] However, since the raw materials required for the production of high-performance concrete have strict requirements, regardless of the mud content of sand and stone or the fineness of fly ash and the amount of fire, there are strict requirements for high-efficiency water reduction in the construction of high-performance concrete. The requirements for the water reducing agent are also strict, both the water reducing rate of the water reducing agent and the air-entraining component of the water reducing agent will affect the quality of high performance concrete

[0004] At present, the high-efficiency superplasticizers on the market have single performance, only have the function of water reduction, and the antifreeze performance is not good enough, and the cement adaptability of different manufacturers is different. It must be compounded with other materials to change its adaptability, and it is difficult to control.
