PRODUCT NAME:Polycarboxylate Superplasticizer

Polycarboxylate Superplasticizer is a high-performance water reducer and a cement dispersant used in cement concrete applications. Widely used in highway, bridge, dam, tunnel, high-rise building and other engineering projects.
This product is environmentally friendly, non flammable, non explosive, and can be safely transported by train and car.
In many concrete engineering projects, traditional high-efficiency concrete such as naphthalene series is increasingly unable to meet engineering needs due to limitations in technical performance. The new generation of water reducers, polycarboxylate based high-performance water reducers, which have attracted much attention both domestically and internationally, have been designed with effective molecular structures based on the mechanism of dispersed cement. They are highly dispersed and can prevent concrete slump loss without causing significant retardation. They exhibit high plasticizing effects at low dosages, good flowability retention, wide adaptability to cement, large freedom in molecular structure, multiple synthesis technologies, and great room for high-performance. They have significant reinforcement effects on concrete, can reduce concrete shrinkage, and have extremely low levels of harmful substances. These technical performance characteristics endow concrete with excellent construction and ease, good strength development, excellent durability, and polycarboxylate based high-performance water reducers have good comprehensive technical performance advantages and environmental protection features. Meet the needs of modern concrete engineering. Therefore, polycarboxylate based high-performance water reducers are gradually becoming the preferred additives for preparing high-performance concrete.
