Types and functions of polycarboxylic acid water reducing agent accelerator admixture for concrete

Types 1. Classified by chemical structure: ether polycarboxylic acid water reducing agent, the main chain and the branch chain are connected by ether bond; amide/imide-type copolymer, grafted with EO/PO halogen-nitrogen compounds on the copolymer; amphoteric copolymer, with unique dispersing ability in the concrete water-cement ratio lower than 0.15.

Classified according to the performance characteristics: standard polycarboxylic acid water-reducing agent, with general water-reducing effect and enhancement; retarder-type polycarboxylic acid water-reducing agent, which can prolong the initial and final setting time of concrete; early-strength polycarboxylic acid water reducing agent, which can accelerate the development of the early strength of the concrete; high water retention-type polycarboxylic acid water reducing agent with excellent water retention properties.
Third, according to the classification of product form: solid polycarboxylic acid water reducing agents, such as tablet water reducing agents, powder water reducing agents, transport and storage is relatively convenient; liquid polycarboxylic acid water reducing agents, the dissolution speed is fast, and the mixing uniformity with concrete mix is good, and it is convenient to measure the use.

Fourth, according to the composition classification: single polycarboxylic acid water reducing agent, formed by a single polymer group; composite polycarboxylic acid water reducing agent, formed by a variety of different types or functions of polymer groups mixed.

V. Functions.

1. Improve the working performance: improve the fluidity, make the dispersion between cement particles so that the concrete is easier to mix, pump and pour in the construction; improve the ease of use, reduce the phenomenon of water seepage and segregation, so that the concrete in the construction of a more uniform and stable.
2. Improve mechanical properties: reduce water consumption, significantly reduce the water consumption of concrete when keeping the fluidity unchanged, improve strength and durability, enhance the strength of concrete, accelerate the development of early strength of concrete, and continue to improve the strength in the late stage.
3. Enhance the durability performance: reduce shrinkage, reduce the volume shrinkage of concrete and crack generation, and improve the durability and stability of concrete structures.
4. With environmental benefits: the production process is pollution-free, does not contain formaldehyde and other harmful substances, is in line with environmental requirements, and in use, will not cause pollution to the environment.
5. To achieve multifunctionality: can be compounded with retarder, early strength agent, impermeable waterproofing agent, etc., to meet the needs of different projects.
