Red mud is a highly alkaline waste by-product of the aluminum industry. Although recycling of red mud is being actively researched, a feasible technological solution has not been found yet. In this study, we propose that neutralization of red mud alkalinity could assist in its use as a construction material. Neutralized red mud (LRM + S; pH 6-8) was prepared by adding sulfuric acid to liquefied red mud (LRM; pH 10-12). After adding LRM and LRM + S to cement paste, the heat of hydration, compressive strength, a
