For polycarboxylate water-reducing agents with high solid content or high parameters, the water-reducing rate can reach more than 40%

I have never seen it reach more than 50%. In actual production, It is also not applicable. One is a cost issue and the other is a construction issue.

The polycarboxylic acid series is generally less than 45%

The naphthalene series is generally only a dozen, less than 30%

The polycarboxylic acid series high-performance water reducing agent is It is the third generation of high-performance water-reducing agent developed after the ordinary water-reducing agent represented by wood calcium and the high-efficiency water-reducing agent represented by naphthalene series.
