Water reduction agent is a commonly used concrete additive, which is mainly used to reduce the water -asx ratio in concrete to improve the liquidity and plasticity of the concrete. The working principles and functions of the water reduction agent are as follows:
Diversified effects: The water reducing agent can form a adsorption layer on the surface of the cement particles, so that the electrostatic exclusion between the particles is increased, thereby improving the decentralized state of the concrete. This helps reduce the viscosity of concrete, improve liquidity, and prevent water from gathering in concrete.
Reduce cement adhesion: The water reducing agent is absorbed to the surface of the cement particles to reduce the adhesion between cement particles. This makes the particles easier to disperse in the concrete, and reduce the mutual attraction between cement particles, thereby reducing the viscosity of concrete.
Surface tension adjustment: The water reduction agent can also regulate the surface tension in the concrete, making the moisture easier to be absorbed and dispersed into the entire concrete system. This helps improve the infiltration and plasticity of concrete.
Control water -grade ratio: The addition of water reduction agents can reduce the amount of water required in concrete, so it can reduce the concrete water and gray ratio. By reducing the water and gray ratio, the strength and durability of the concrete can be improved.
In general, the water reduction agent can improve the liquidity, plasticity and working performance of concrete by dispersing cement particles, reducing adhesion, regulating surface tension, and controlling water -asx ratio. They are widely used in concrete engineering, improving construction efficiency and the quality of concrete products.
