N2 - Magnesium potassium phosphate cement (MKPC) is a type of chemically bonded phosphate ceramic whose hydration requires effective control to ensure adequate workability and stable performance. This study investigates sugar beet molasses (SBM), a carbohydrate rich agro-industrial by-product, as a bio-based admixture for regulating MKPC hydration. MKPC pastes containing SBM (SBM-to-MgO mass ratios of 0.1–0.5) were evaluated in terms of hydration temperature, early-age compressive strength, physical properties, phase composition, and microstructure. SBM effectively moderated hydration by reducing the peak temperature and redistributing heat release over time. Moderate SBM dosages enhanced early compressive strength while reducing water absorption and accessible porosity. XRD and FTIR confirmed that SBM preserved the struvite-dominated phase assemblage, whereas SEM revealed refined hydration products and a denser matrix. Overall, SBM acts as an effective bio-based hydration regulator, improving the early-age performance and physical properties of MKPC while promoting the valorization of an agricultural by-product.
