Since the molecular structure of the polycarboxylate water reducer contains a large number of carboxylic acid groups, the carboxylic acid groups lose negative charge under acidic conditions, so that the dispersibility of the water reducer is reduced, and the water reducing effect is affected.

Therefore, in the concrete preparation process, it is necessary to adjust the pH value in the concrete by adding an appropriate amount of alkaline substances to ensure the performance and durability of the concrete.
