Water reduction agent is a commonly used concrete additive that can play a role in controlling water -asx ratio, improving liquidity, and reducing cement dosage in concrete. Its main working principle and role are as follows:
Diversified effects: The water reduction agent has the characteristics of the surface active agent. By adsorbing the surface of the cement particles, it forms a material layer with a negative charge, so that the cement particles are static and charged, and the reprimand is mutual to achieve the decentralization of the cement particles. This decentralized effect can effectively reduce the gathering of cement particles and improve the liquidity of concrete.
Reduce adhesion: The water reduction agent will also form a adsorption layer on the surface of the cement particles, which reduces the adhesion between the particles, reduces the mutual adsorption of the cement particles, thereby reducing the internal friction resistance of the concrete.
Reducing surface tension: The water reduction agent can reduce the surface tension of water, making it easier to penetrate and fill the small gap in concrete, and improve the liquidity of concrete.
Delaying the condensation time: Some water reducing agents also have the effect of delaying concrete condensation time, so that the concrete has a long adjustable and working time.
The role of water reduction agent is mainly reflected in improving the liquidity and processability of concrete, while reducing the amount of cement and improving the strength and durability of concrete. By using the water reduction agent, the requirements for concrete can be achieved in engineering construction, improve the efficiency of concrete construction, and reduce costs. It should be noted that the use of water reducing agents should be controlled strictly in accordance with relevant standards and suggestions to control the dosage and follow the requirements of the construction process.http://www.krchemical.com/shuichuliji-01.htm
