Mechanism and CO2 emissions analysis of multi-solid-waste synergistic red mud-based composite cementitious materials under orthogonal tests
Published 2025-01-01“…The results revealed that: (1) Range analysis indicated that the factors influencing the 28 d compressive strength ranked as follows: quicklime (C) > silica fume (B) > fly ash (A). The optimal combination was determined to be A2B3C4, achieving a maximum compressive strength of 25.13 MPa with 53% RM. (2) Variance analysis revealed that F (fly ash) = 3.961 < F0.01, F(silica fume) = 17.778 > F0.01, and F(quicklime) = 61.921 > F0.01, 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. (3) Microscopic analysis showed that the strength improvement contributed by fly ash and silica fume was mainly attributed to their good potential pozzolanic activity and microaggregate filling effect. …”
