Water reduction is a chemical additive widely used in concrete and cement products. It can reduce the amount of cement by changing the physical and chemical properties of the cement slurry.
The main reason is as follows:
Reduce water -grade ratio: The water -reducing agent can reduce the water -grade ratio in the concrete, that is, the quality ratio of the water to the cement. By using the water reducing agent, the amount of water required can be reduced while maintaining the liquidity of concrete, thereby reducing the amount of cement.
Improving liquidity: The water reduction agent can make the concrete have better liquidity and plasticity. This can improve the work performance of concrete without changing the cement collagen structure, thereby reducing the amount of cement.
Enhanced decentralization: The water reduction agent can form a charge in the concrete and cause decentralized effects to prevent the accumulation of cement particles. This can improve the uniformity and strength of the concrete and reduce the amount of cement.
It should be noted that the use of water reducing agents must be controlled and adjusted in accordance with relevant regulations and standards to ensure the performance and quality of concrete. In addition, when selecting and using a water reduction agent, a reasonable ratio and test should be conducted according to the specific engineering requirements and conditions.
