Polycarboxylic acid high performance water reducer CAS 62601-60-9
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.
