Abstract

Sulfonated melamine-formaldehyde polycondensates, prepared according to a novel procedure, were tested and evaluated as concrete superplasticizers. The effect of cement type and brand, airentraining agents, and retarders on the performance of these admixtures in concrete was studied. The effect of curing medium and curing time on the performance of these materials was also evaluated. These novel admixtures were evaluated and compared with commercially available melamine-based superplasticizers. Results show that the various additives used have no effect on the performance of these resins. The resins outperformed commercial melamine-based superplasticizers by 10 to 20% in compressive strengths of concrete and 20 to 40% in the case of concrete workability.
