Three generations of superplasticizer chemistry are currently available to concrete admixture producers and ready-mix concrete operators across Southeast Asia, Europe, and Asia: naphthalene-based, melamine-based, and polycarboxylate-based. All three reduce water demand in concrete. All three improve workability at lower water-cement ratios. But their performance differences in water reduction efficiency, slump retention, dosage requirement, and compatibility with modern concrete mix designs are significant enough that choosing the wrong generation for your application produces concrete that underperforms specifications or costs more than necessary to produce. This article compares all three on the parameters that matter most for concrete production decisions.
