Water reduction is a chemical agent commonly used in concrete and mortar preparation. Its main function is to reduce the amount of concrete or mortar, while improving its working performance. The following is the main role of water reducing agent:
Reduction of water -grade ratio: The water reduction agent can significantly reduce the amount of moisture required in concrete or mortar while maintaining proper operability. By reducing the ratio of water and gray (that is, the ratio of water and cement), the strength and durability of concrete or mortar can be improved.
Improving liquidity: The water reduction agent can improve the liquidity and plasticity of concrete or mortar, making it easier for them to construction, pour and vibrate, and reduce resistance. This helps improve construction efficiency, reduce labor intensity, and ensure that concrete or mortar is fully filled in the mold.
Increasing early intensity: Some water -reduction agents can also improve the early intensity of concrete or mortar by promoting early hydration reactions of cement. This is very valuable for the structure that needs to be quickly used or early load.
Improve durability: Proper use of water reducing agents can reduce pores and defects in concrete or mortar, and improve their denseness and durability. This helps to reduce the damage caused by factors such as water penetration and chloride ion penetration.
Adjusting condensate time: certain water reduction agents have the ability to control concrete or mortar condensation time. By adjusting the condensation time, different construction requirements and environmental conditions can be met.
It should be noted that the use of water reducing agents should be controlled according to the specific situation and needs, and strictly follow the instructions and suggestions of the use of manufacturers. Excessive use of water reducing agents may cause the performance of concrete or mortar to decrease, and even affect its strength and durability.
