polycarboxylate superplasticizer

polycarboxylate superplasticizer is a kind of performance admixture, and it is a kind of concrete thickener in concrete application. It is widely used in roads, highway bridges, dams, tunnel construction, multi-story buildings and other engineering projects.

According to the different carbon chain structure, the commercial products of polycarboxylated concrete water-reducing agent can be divided into two categories: one is with acrylate or methacrylic acid as the main chain, and methacrylate with different main chain length is grafted. The other is to use maleic anhydride as the leading linker of methacrylates with different main chain lengths. Based on this, a series of performance additives products with different characteristics have been derived.

What are the functions of polycarboxylate superplasticizer ?

The alkali water content and chloride ion content are minimal, and the polycarboxyl hydrolyzate will have no rust damage to the building steel bars after mixing, and has no negative impact on the concrete. In addition, the product has no protein denaturation or crystallinity at ultra-low temperature, so it is convenient to use.

It is beneficial to improve the cohesiveness of concrete mixtures, reduce bleeding, and improve the appearance and performance of hard bottomed concrete, especially in the application of pervious concrete engineering projects.

The concrete equipped with polycarboxylic acid water-reducing agent hydrolyzate is not prone to obvious concrete cracks and bleeding, even in the case of high slump, and the appearance of the concrete is uniform in color. When used to equip standardized concrete, the concrete has good workability and strong cohesion, and the concrete is good for mixing.

Polycarboxylic acid water-reducing agent is very important for construction projects. Note that it must be added according to the proportion when using it, so that the polycarboxylic acid water-reducing agent can achieve the best practical effect.
