Do you know about the four common types of concrete water-reducing agents?

Water reducing agent is a functional additive commonly used in concrete projects. It can effectively reduce water and strengthen it without affecting the workability of concrete. Therefore, its application in the market has become more and more widespread. The domestic concrete market has gradually promoted its application, especially in high-strength concrete and pumped concrete, where it has become an indispensable component. So what are the most commonly used water reducing agents on the market currently, and what are their characteristics?

According to (GB8075-87) classification, concrete admixtures can be divided into four categories according to their main functions:

Admixtures that improve the rheological properties of concrete mixtures: including various water-reducing agents, air-entraining agents and pumping agents, etc.

Admixtures that adjust the setting time and hardening performance of concrete: including retarder, early strength agent, accelerating agent, etc.

Admixtures that improve the durability of concrete: including air-entraining agents, waterproofing agents, and rust inhibitors.

Admixtures to improve other properties of concrete: including air-entraining agents, expansion agents, antifreeze agents, colorants, waterproofing agents and pumping agents, etc.

First, air-entraining water-reducing agent

Air-entraining water-reducing agent is a water-reducing agent with unique functions. In addition to water reduction and enhancement functions, It also has an air-entraining effect.

Second, high-efficiency water-reducing agent

Compared with ordinary water-reducing agents, high-efficiency water-reducing agents for concrete have greater water reduction and better reinforcement effects. It is the best-selling mainstream water-reducing agent category on the market today.

Third, retarded water-reducing admixture

Compared with other water-reducing admixtures, retarded water-reducing admixtures not only have water reduction and enhanced functions, but also have unique The retarding effect is suitable for some projects that have special requirements for concrete solidification.

Fourth, ordinary water-reducing agent

Ordinary water-reducing agent refers to a water-reducing agent with general water-reducing and reinforcing effects. It is mainly used to meet the water-reducing performance requirements of concrete. Low-priced home construction and decoration and infrastructure fields.

The above four types of water reducing agents account for a large part of the total amount of water reducing agents currently sold on the market. However, concrete water reducing agent dry powder manufacturers believe that as people’s requirements for concrete performance increase, there will be more water reducing agents on the market. More products with better performance and more stable effects have become the mainstream of the market.
