What is Polycarboxylate Water Reducer?

What is polycarboxylate water reducer?

Polycarboxylate water reducing agent is divided into water agent and powder agent according to the different appearance. The solid content of polycarboxylate water reducer is generally 20%, 40% (also known as mother liquor), and 60%, and the solid content of polycarboxylate water reducer powder is generally 98%.

Polycarboxylate water reducer is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete basically unchanged. Most of them are anionic surfactants, such as lignosulfonate, naphthalene sulfonate formaldehyde polymer, etc. After adding the concrete mixture, it has a dispersing effect on the cement particles, which can improve its workability, reduce the unit water consumption, and improve the fluidity of the concrete mixture; or reduce the unit cement consumption and save cement.

What are the additives?

Concrete admixture is a chemical substance that is added in the process of mixing concrete, accounting for less than 5% of the cement mass, and can significantly improve the performance of concrete. The characteristics of concrete admixtures are many varieties and small dosage, which have a great influence on the performance of concrete, and have the characteristics of less investment, quick effect, and significant technical and economic benefits.

Admixtures can improve the anti-carbonation performance of concrete to a certain extent. There is a certain linear relationship between the carbonation depth and porosity of concrete. Admixtures have a great influence on the frost resistance of concrete. It has good performance, but the single addition of early strength agent has no effect on the frost resistance of concrete.

What are the concrete additives?

  1. Admixtures to improve the rheological properties of concrete mixtures.

Including various water reducing agents, air entraining agents and pumping agents, etc.

  1. Admixtures for adjusting the setting time and hardening properties of concrete.

Including retarders, early strength agents and accelerators.

  1. Admixtures to improve the durability of concrete.

Including air-entraining agent, waterproofing agent and rust inhibitor, etc.

  1. Admixtures to improve other properties of concrete.

Including air entraining agent, expansion agent, coloring agent, antifreeze agent, water repellent agent and pumping agent, etc.

Concrete has the characteristics of abundant raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades.

These characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material.
