This product is a new generation of environmentally-friendly polycarboxylic acid high-performance hydrazine type water reducing agent developed by our company. Under the alkaline condition, the hydrazine type itself undergoes hydrolysis reaction, thereby releasing carboxylic acid groups with dispersing properties. Achieve a long-lasting dispersion effect, in addition to excellent sealing performance, it also has a certain water reducing effect, and significantly improves the cohesiveness of concrete and improves the concrete performance.
Product technical performance
1. Special molecular structure and special branch structure design, which is used for hydrolysis reaction in fresh concrete. By adjusting the branch structure, the hydrolysis rate can be adjusted within the effective time to achieve selective protection effect.
2. Slow release property,This product is blended into concrete, slowly hydrolyzed, releasing carboxylic acid groups to achieve long-lasting dispersion effect, achieving ideal preservation effect.
3. The higher strength increase rate, the concrete mixed with the product does not change the setting time, overcomes the shortcomings of the general retarder to make the concrete final setting time too long, and the early strength development is too slow.
Product Uses
pce slump retention type concrete water retaining agent
polycarboxylate superplasticizer can be used for precast concrete,SCC concrete,ready mix concrete,self-leveling mortar,etc.

Instructions
The recommended range of product is 0.35%~0.65%. The specific amount of cement and mix ratio should also be determined by experiment.
This product has a low water reduction rate and is recommended for use in combination with a water-reducing mother liquor. The optimum compounding ratio should be determined according to the test. This product can be combined with various functional admixtures such as polycarboxylate water reducer and various retarder air entraining agents. The best compounding should be determined through experiments before use.
Precautions
This product is an alkali-free liquid, non-toxic, non-corrosive liquid, no pollution to the environment, not edible
If you accidentally touch your eyes, rinse them with clean water as soon as possible, causing allergies to some people. You should seek medical treatment promptly.
