The document summarizes a study on the mechanical characterization of cementitious materials made with red mud, a waste product from aluminum production. Specifically, it examines the compressive strength of cubes made with varying percentages (5-13%) of lime or cement added to a mixture of red mud, sand, and water, and cured for 7, 14, or 21 days. The results showed that cubes with 13% lime cured for 21 days achieved the highest compressive strength of 5.46 N/mm2, making it suitable for use in pavement blocks. In general, cubes with lime achieved higher strengths than those with cement, due to lime's higher calcium oxide content.
