Polycarboxylic acid water reducer is a kind of unsaturated monomer containing carboxyl group and unsaturated monomer containing other functional groups. Compare with other water-reducing agents, it has that advantage of low dosage, high water-reducing rate, controllable molecular structure, good dispersibility, environmental protection and strong adaptability, which can greatly improve the early and late strength of concrete and building mortar, reduce the exothermic rate of cement hydration, and thus facilitate the opening time of construction.
| project | index |

Used for grouting material, duct grouting material, bearing mortar and repair mortar of ordinary portland cement, it has the advantages of high water reducing rate, excellent fluidity, strong compatibility of formula, long-term stability and easy storage.
Used in cement-based leveling layer and self-leveling system, with sulphoaluminate cement as main material system. The product has the advantages of high water reducing rate, excellent adaptability and stability, excellent fluidity, wide PH value applicability, and excellent workability and mechanical strength.
It is used for super-performance high-performance concrete (UPHC), with high slurry fluidity, good retention, long operation time, no bleeding and excellent construction performance.
Used in gypsum-based system and gypsum-based self-leveling mortar.
Used in gypsum-based products, the performance is more stable, and it has the advantages of high water reduction, high fluidity and strong adaptability with other additives.
The addition amount varies according to the application scope, region and formula, and the general addition amount accounts for about 0.05%-0.5% of the cementitious material. When the dosage is high, it is suggested to do adaptability test to avoid bleeding and segregation or the influence on setting time.
