Experimental Investigation of Mixing Desulfurization Residues and Cement
Disposition and utilization of desulfurization residues from thermal power plants in Portland cement was investigated, controlling the content of SO3 at 3.0%(in mass), thus exploring the application feasibility of desulfurization residues in cement industry by the analysis of recombination mechanisms between desulfurization residues and Portland cement. The results show that desulfurization residues can improve physical-mechanical properties of cement: increasing the strength at various ages; improving the water requirement for normal consistency; regulating the setting time effectively, etc. Different desulfurization residues and different additions have different effects on the performance of Portland cement.
