In this study, the feasibility of using waste materials to manufacture Portland cement was investigated. Reagent‐grade chemicals were used to synthesize a Portland cement clinker with a tightly controlled composition. Then, calcium oxide‐bearing waste materials, specifically fly ash and blast furnace slag, were combined with the reagent‐grade chemicals. The synthetic cements were characterized using X‐ray diffraction, scanning electron microscopy, and isothermal calorimetry. Results show that Portland cement can be successfully synthesized by replacing reagent‐grade chemicals with up to 40% fly ash and 60% slag incorporation. These synthetic cements possess early‐age hydration behavior similar to a commercial Type I/II Portland cement.
