Supersulfated cement (SSC) is a specialized cement comprising ≥75%wt granulated blast-furnace slag (GBFS), 5-20%wt calcium sulfate (gypsum or anhydrite), and ≤ 5%wt Portland cement clinker. SSC exhibits exceptional performance, including high resistance to sulfate solutions, peaty acids, oils, and other contaminants in wastewater and soil. Furthermore, its high slag content, surpassing 75%, contributes to reduced CO2 emissions, making SSC an environmentally sustainable choice for cement production. This study investigates the effects of weak acid salt agents (citrate and tartrate) added during mixture preparation, as well as different curing conditions, on the properties of SSC mortar. Different material characterization techniques were employed to perform a comprehensive analysis of the phase assemblage, such as X-ray diffraction (XRD) and scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectroscopy (EDS). The results demonstrate the abundant ettringite (E) formation in the hydrated cement product, particularly when exposed to rich sulfate ion solutions. Additionally, the research highlights the significant impact of temperature-stimulated curing conditions on accelerating the hydration reaction of SSC. These experimental findings provide deeper insights into the factors influencing SSC's hardening and strength development. The findings of this study provide valuable information for enhancing the efficiency and usage of SSC in the construction industry, which aligns with the goal of sustainable development.
