High-Temperature Release of SO2 from Calcined Cement Raw Materials
During combustion of alternative fuels in the material inlet end of cement rotary kilns, local reducing conditions may occur and cause reductive decomposition of sulfates from calcined cement raw materials. Decomposition of sulfates is problematic because it increases the gas-phase SO2 concentration, whichmay cause deposit formation in the kiln system. In this study, the release of sulfur from ...

During combustion of solid fuels in the material inlet end of cement rotary kilns, local reducing conditions can occur and cause decomposition of sulfates from cement raw materials. Decomposition of sulfates is problematic because it increases the gas-phase SO2 concentration, which may cause deposit formation in the kiln system.

متن کاملSynthesis and Characterization of High Belite Sulfoaluminate Cement through Rich Alumina Fly Ash and Desulfurization Gypsum
The objective of this study was the preparation and characterization of high belite sulfoaluminate cement (HBSC) from industrial residues. HBSC promises eco-friendly building materials with great mechanical performance at earlier ages than Ordinary Portland Cement (OPC). Preliminary results show the formation of main phase dicalcium silicate (C2S) and ye’elimite (C4A3$) at 1250°C, as determined...
متن کاملUtilization of Eaf Metallurgical Slag in “green” Belite Cement
În acest studiu, zgură de cuptor cu arc electric (EAFS) colectată de la Sovel S.A., Grecia şi calcar şi argilă, de la compania de ciment Titan S.A., Grecia, au fost utilizate pentru producerea şi caracterizarea cimenturilor tip belitice. Trei tipuri de clincher au fost preparate: belitic fara adaos de zgură folosit ca referinţă (BC), unul cu 5wt% EAFS (BC5) şi un altul cu 10wt% EAFS (BC10). Ana...
متن کاملEffect of Calcium Carbonate Fineness on Calcium Sulfoaluminate-Belite Cement
This study investigated the hydration characteristics and strength development of calcium sulfoaluminate-belite (CSAB) cements incorporating calcium carbonate (CC) powders with various particle size distributions and different gypsum amounts. In general, the CSAB hydration was accelerated by the CC powder, but the acceleration and resulting strength improvement were more effective with finer CC...
