Polycarboxylic acid high performance water reducer
Polycarboxylate superplasticizer (PCE) is a new generation of high-performance superplasticizer. It is developed after the common water reducing agent represented by wood calcium and the high-efficiency superplasticizer represented by naphthalene series. At present, PCE is a superplasticizer with the best application prospect and the best comprehensive performance. So it can be widely used in highways, bridges, dams, tunnels, high-rise buildings, and other projects.
Polycarboxylate superplasticizers have become one of the most important superplasticizers in the concrete admixture market, that’s due to its outstanding advantages, such as high water-reducing rate, good effect, good adaptability with cement, and slump protection performance. With the construction of large-scale infrastructure such as nuclear power, water conservancy, bridges, tunnels, etc., especially the implementation of planning and railway passenger dedicated line network projects, the market demand for PCE polycarboxylate superplasticizers will show a trend of continuous growth.
As a new type of green concrete admixture, polycarboxylate superplasticizer is very suitable for high-strength concrete, high-performance concrete, mass concrete and high-quality fluid plastic concrete. And PCE superplasticizer has the features of water reduction, slump retention, reinforcement, shrinkage resistance, and environmental protection. In addition, it can also be compounded with various admixtures into multifunctional concrete admixtures, such as pumping agent, early strength agent, impermeable waterproofing agent, retarder, etc.

1, White polycarboxylate powder is a new generation of environmentally friendly high-efficiency water reducing agent for mortar based on new synthesis technology. The main component is polycarboxylate, which is a fluid powder made by special drying technology. And its comprehensive indicators are excellent, green and pollution-free, so PCE powder is the high-performance environmentally friendly product.
2, PCE based superplasticizer (High Water Reduction) is the light yellow liquid, it can greatly reduce the water consumption of cement, increase the fluidity of concrete, and improve the crack resistance of cured cement. It can be widely used in non-shrinkage grouting, repair mortar, etc.
3, Polycarboxylate superplasticizer (High Slump Retention) is clear transparent liquid. It keeps the slump of concrete well, and can prolong the slump retention time of concrete. What’s more, PCE superplasticizer also shows great performance in hot environments.
