Polycarboxylate superplasticizer 16

High-performance superplasticizers include polycarboxylic acid superplasticizers, aminocarboxylic acid superplasticizers and other superplasticizers that can meet the requirements of high-performance superplasticizers in the Concrete admixture GB8076-2008 standard. China's high-performance water reducing agents are mainly represented by polycarboxylic acid series high-performance water reducing agents. Hongyun is committed to the production of polycarboxylic acid high performance water reducer.

High performance superplasticizer is a new type of admixture developed at home and abroad in recent years, mainly for polycarboxylate products, it has a "comb-like" structure characteristics, with free carboxylate anion group main chain and polyoxyethylene side chain composition, by changing the type of monomer, proportion and reaction conditions can produce a variety of different properties and characteristics of high performance superplasticizer. The high performance superplasticizer of early strength, standard type and retarding type can be produced by introducing different functional groups by molecular design, and can also be mixed with different components.

1, the content is low (according to the solid content calculation, generally 0.15% to 0.25% of the quality of the cementing material), high water reduction rate;

2. The workability and workability retention of concrete mix are good;

3, the content of chloride ion and alkali in the admixture is low;

4. The shrinkage rate of concrete prepared with it is small, which can improve the volume stability and durability of concrete;

5, good adaptability to cement;

6, the production and use process does not pollute the environment, is an environmentally friendly admixture.
