Polycarboxylate superplasticizer is a new type of water-reducing agent prepared by monomer multi-component water-based polymerization water reducer. Due to the unique molecular structure, the water reducing agent can realize the dispersion of cement particles through the dual action of electrostatic repulsion and steric barrier, showing excellent dispersibility and dispersion retention ability. This product has the advantages of low dosage, high water reducing rate, good reinforcement effect, low total alkali content, non-corrosion of steel bars and environmental friendliness. The third-generation high-performance water-reducing agent developed after the water-reducing agent is currently the most advanced water-reducing agent in the world, with the highest technological content, the best application prospect and the best comprehensive performance.
Polycarboxylate superplasticizer has better slump retention under the condition of good adaptability to the materials used.
The slump loss of concrete in 1.5h is very small, generally not more than 15%, which is extremely beneficial for long-distance transportation of concrete.
The concrete mixture prepared with polycarboxylate superplasticizer has good work ability and good cohesion.
It has certain air-entertaining properties, which can increase the air content of concrete by more than 2%.
The change of the mixing ratio has a certain influence on the air entertaining property of the polycarboxylate superplasticizer, and the increase of the air content has no obvious adverse effect on the strength.
It has a good strengthening effect on hardened concrete, and the strength growth is stable, generally 7 days
The strength can reach about 100% of the design strength, and the strength continues to increase in the later stage.
The molecular structure has a large degree of freedom, and there are many controllable parameters in the additive manufacturing technology.
Polycarboxylate superplasticizers with special properties and uses can be prepared by adjusting the molecular structure, which is convenient to meet the needs of environmental changes on the construction site.
The product is green and environmentally friendly, and does not contain harmful ingredients that pollute the environment and affect human health.
The advantages of polycarboxylate superplasticizers are obvious to all, unmatched by other types of superplasticizers. As long as we look at these problems from a systematic and developmental perspective, strengthen the cooperation and coordination between producers and users of superplasticizers, including cement manufacturers, give full play to the advantages of polycarboxylate superplasticizers, and strive to overcome their shortcomings, The application prospect of polycarboxylate superplasticizer will be broader.
