Preparation of Polycarboxylic Acid Type Water Reducing Agent

With the rapid development of high-performance concrete, the technology of polycarboxylic acid type water reducing agents has also made tremendous progress. Polycarboxylic acid type water reducing agents have high water reducing rate, excellent slump performance, and can ensure low shrinkage rate of concrete. Polycarboxylic acid water reducing agent does not add formaldehyde during the production process, which is green, environmentally friendly, non flammable, and non explosive. It can be safely transported by train and car. These advantages greatly promote the application of polycarboxylate water reducing agents. However, in practical engineering applications, polycarboxylic acid type water reducing agents have poor adaptability to different types of cement, resulting in their performance not being fully utilized. Therefore, it is particularly important to mix polycarboxylic acid type water reducing agents.
