Polycarboxylic Acid Series High-Performance Water Reducer
1. High water reduction rate:lt can make the water reduction rate reach more than 25%, in the case of the same water addition of concrete, it can greatly improve the fluidity;
2. High slump retention:Due to the role of high temperature, the carboxylic acid groups of traditional polycarboxylic acid powder water reducer will be damage more or less to some extent during the spray drying process. Thus, the slump retention performance of liquid converted into solid is greatly reduced. NC-904 is manufactured with a special process, so that the carboxylic acid groups are not damaged during the powder manufacturing process, thus preserving the slump retention of the mother liquor of original solution.
3. Good solubility and fast dissolution rate:Due to its uniform particles, the specific surface area is large. So it dissolves very quickly during the water dissolution process. And there are no obvious impurities after dissolution.

Polycarboxylic Acid Series High-Performance Water Reducer
1. Special molecular structure: special branch chain structure design is used for hydrolysis reaction in fresh concrete. By adjusting the structure of the branch chain, the hydrolysis rate of any adjustment period can be arbitrarily adjusted within the effective time, so as to achieve the selective slump retention effect.
2. Slow release: after the product is incorporated into concrete, the slow hydrolysis occurs. After hydrolysis, the original macromolecule releases carboxylic acid group, while a small amount of small molecule substances has a certain dispersion effect. Hydrolysis gradually ends over time and finally terminates.
3. Economy: this product has certain water reduction performance, and its water reduction rate can reach 50% of that of the water reducer mother solution of the same type, which can significantly lower the dosage of water reducer in the same system and reduce the economic cost.

Cement Admixture
This product is made of polyol molecules based on molecular modification. By adding functional groups with strong complexation ability, the dispersibility of the product is improved, and the induced hydration ability of the synthetic
product is also improved. The direct single use or combination of other materials as grinding aid can ensure the strength of the cement while ensuring the grinding aid. This product can reduce the dependence of grinding aid on high-priced chemical raw materials (such as triethanolamine), while without adverse effect on the strength of cement in the later stage, and it can also ensure the performance of concrete in the later stage. The product is chlorine-free, non-flammable and green.
