Abstract

This study examines the thermal and functional properties of a superplasticizer based on a naphthalene sulfonate–formaldehyde condensate in cement systems. Differential thermal analysis (DTA) revealed endothermic effects in the range of 50.23–782.49 °C; the mass loss was 11.568% at 19.49–154.31 °C and 37.834% at 681.44–951.50 °C. The addition of 0.2–1.0% superplasticizer increased the flow of the cement paste by a factor of 1.5–2.5 and the 14-day compressive strength by 4–12%. The results confirm the effectiveness of the admixture for modifying cement compositions.
