Due to the low softening point, ordinary polycarboxylate superplasticizers cannot be powdered by spray drying. Molecular design to increase softening point without losing water-reducing performance yields high-content powdered polymers.

Polycarboxylate water-reducing agents has the properties of high water reduction and high slump retention, and can impart high strength and durability to concrete. It has shown outstanding advantages in high-quality projects such as national large-scale water conservancy, nuclear power, and bridges. Compared with naphthalene-based water-reducing agents, polycarboxylate water-reducing agents are sensitive to the mud content of sand and gravel aggregates [1-3] and are expensive. Therefore, in laboratories and engineering construction, attempts have been made to mix polycarboxylate water-reducing agents and naphthalene-based water-reducing agents to take advantage of their respective advantages.

Due to its excellent properties, polycarboxylate superplasticizers are widely used in many fields, including:

Concrete admixture is an important guarantee for the improvement of concrete performance. As an important admixture, water reducing agent can significantly improve the workability and physical and mechanical properties of concrete.
