Ordinary water-reducing agents have a good dispersion effect on cement and other cementitious materials in water, thus improving the fluidity of cement mixtures and reducing water consumption while maintaining fluidity. Generally, the water reduction rate is 10%. The following, while significantly improving concrete working properties such as workability, etc.
There is slight or moderate retardation that delays the solidification of concrete for 1-4 hours, so it should be used with caution in the production of concrete products that use steam curing processes.
Because it can reduce water consumption, adding ordinary water-reducing admixtures can make the strength of concrete at all ages higher than that of benchmark concrete without mixing. The 28d strength can be increased by 5-10%.
When the concrete is only required to maintain its original design strength, cement can be saved by 10% or more.
The use of ordinary water-reducing admixtures can significantly enhance the impermeability, frost resistance and corrosion resistance of concrete. It will not cause corrosion to steel bars and improve the durability of concrete.
