There are many types of concrete water reducers in China, but only polycarboxylate high-performance water reducers have particularly obvious advantages.
They have high water reduction, low slump loss, low dosage, non retarding, and are not affected by dosage time.
The water reduction rate is generally above 35%, and the dosage is extremely low, only about 0.
6% to 1.
2% of the total amount of cementitious materials.
After being added to concrete, it can endow concrete with good fluidity, high strength, and low shrinkage rate, and can also reduce the occurrence of alkali aggregate reaction to a certain extent, improving the durability of concrete.
Therefore, becoming a product representing the most advanced technology of concrete admixture materials is the focus of research and development of chemical admixtures.
