Zusammenfassung:As part of a project aimed at preparing an energy-saving cement within the CaO-SiO2-Al2O3-SO3 system having non-expansive properties, clinker was prepared by sintering a mix of industrial raw materials at 1280 C in a laboratory oven. The hydration products of the cement cured to 90 days were studied by SEM, XRD, and TGA. They were found to be similar to those of a typical sulphoaluminate cement. The low rate of hydration of the belite phase was attributed to its microcrystalline form. 20 refs.
