Effect of Sulfonated-Melamine Formaldehyde as Superplasticizer in Cementitious Systems

Abstract. This paper studied the effect of Sulfonated-Melamine Formaldehyde (SMF) on the water cement ratio, setting time, compressive strength at various ages and an acid resistance test was conducted using sulfuric acid. Sulfonated-Melamine Formaldehyde is classified as superplasticizer. SMF was mixed with concrete at 1%-5% in volume fraction. But not much investigation was made. In this study it was found that the Sulfonated-Melamine Formaldehyde incorporated concrete mixture performing well in strength property and have more resistance to aggressive environment when compared to conventional concrete.
