Mechanism and CO₂ emissions analysis of multi-solid-waste synergistic red mud-based composite cementitious materials under orthogonal tests.

(2) Variance analysis revealed that F (fly ash) = 3.961 < F 0.01 , F(silica fume) = 17.778 > F 0.01 , and F(quicklime) = 61.921 > F 0.01 , indicating that fly ash had no significant effect on the 28 d compressive strength, while silica fume had a significant effect, and quicklime had a highly significant effect.
