The water reducing agent refers to a chemical mixture added to the concrete. Its role is to achieve the following effects by improving the liquidity and processability of concrete:
Reduce the amount of cement: The water -reducing agent can reduce the concrete water and ash ratio, reduce the concrete to reach the same intensity, and reduce the amount of cement, and improve the economy of concrete.
Improve liquidity and processability: The water reduction agent can reduce the viscosity of concrete, improve the liquidity of concrete, and make it easier to construct and process. This is very important for structural components with high or complex shape requirements for construction performance.
Increasing concrete strength: The appropriate amount of water reducing agent can improve the decentralization and tightness of the concrete, which is conducive to improving the compressive strength, folding strength and durability of the concrete.
Control condensate time: The water reduction agent can regulate the condensation time of the concrete, delay or accelerate the concrete and hardening process of concrete to meet different construction needs.
Reduce air content: The appropriate amount of water reduction agent can reduce the air content in the concrete and improve the density of concrete and frozen resistance.
It should be noted that the use of water reducing agents should be rationally controlled according to the specific situation, and follow relevant standards and recommended dosage to ensure the performance and quality of concrete.
