Preparation of Calcined Phosphogypsum-Based High-Strength Supersulphated Cement
Based on mechanical properties, the influences of the clinker dosage(C1, C2, C3), calcination temperature(M1, M2, M3) of phosphogypsum(PG) and specific surface area(S1, S2, S3, S4) on the mechanical properties of supersulphated cement(SSC) were systematically studied; Then SSC with different kinds of PG were chose to research water requirement of normal consistency, setting time and soundness; Strengthening mechanism on SSC were further investigated and analyzed with scanning electron microscope(SEM) and chemical composition analyzer at last. Results showed SSC with conditions of C2, T3 and S3 has 36.4, 56.5 and 72.6MPa standard mortar compressive strength at 7d, 28d and 56d curing age. Calcined Phosphogypsum(CPG)-based high strength SSC is successfully developed.
