Different water reducing rates The water-reducing rate of polycarboxylic acid-based water-reducing agents is significantly higher than that of naphthalene-based water-reducing agents. Under the condition of exceeding the same water-reducing rate, the dosage of polycarboxylic acid-based water-reducing agents may be smaller than that of naphthalene-based water-reducing agents; in addition, as the dosage increases, the ultimate water-reducing …
