Study on the interaction mechanism between polycarboxylic acid and naphthalene-based water reducing agent

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.
