Abstract Concrete serves as a core material in building engineering, and its performance directly impacts structural safety and economic efficiency. Superplasticizers act as key chemical admixtures to improve its overall properties. Polycarboxylate superplasticizer demonstrates remarkable advantages in water-reduction rates and slump retention due to its unique molecular structure. Natural sand shortages have driven the widespread …
