Water reducing agent (also known as cement water reducing agent and concrete water reducing agent) is a commonly used architectural chemical agent. It can play a role in reducing water and ash ratio, improving liquidity and working performance in concrete or cement slurry. The main effect of the water reduction agent is as follows:
Reduction of water and gray: The water reduction agent can significantly reduce the amount of water required in the concrete or cement slurry system while maintaining the same liquidity. By reducing the water -toas ratio, the strength, durability and cracking resistance of the concrete can be improved, and contraction and deformation can be reduced.
Improving liquidity: The water reduction agent can improve the liquidity of the concrete or cement slurry system, making it easier for construction and molding. It can increase the plasticity and liquidity of concrete, reduce adhesion and internal friction, and make the concrete more easier to flow and enrich during the construction process.
Improve working performance: The water reduction agent can significantly improve the working performance of concrete, including improving the slump, delaying condensation time, and improving water resistance. It can make concrete better uniformity, controllability and operability, and it is easier to pour, vibrate and maintain during the construction process.
Improve the quality of concrete: water reduction agent can improve the density and structural performance of concrete, thereby improving the quality of concrete. It can reduce the formation of pores and cavities, improve the density and durability of concrete, and increase the strength and durability of concrete.
It should be noted that the effect of water reducing agents is affected by various factors, including the type, dosage, cement types, aggregate characteristics, climate conditions, etc. of the water reduction agent. Therefore, when using a water reduction agent, it is necessary to follow the suggestions and instructions of the supplier of the water reduction agent to perform accurate proportion and tests to obtain the best water reduction effect and concrete performance.
