Sažetak
Over again, much attention has been given to the development of special cement clinkers, leading to energy saving and better environmental management. One of such cements is the calcium sulfoaluminate cements (CSAC), an economical and environmental friendly alternative to Portland cement. The key mineral of CSAC is the Klein’s compound (4CaO·3Al2O3·SO3 i.e. C4A3s in shortened cement mineralogy notation), because of its hydration reaction ability to produce ettringite. C4A3s based cements are used commercially in increasing quantities, but several aspects of its solid state production as well as hydraulic reactivity appear to be difficult to control. It is known that iron-aluminum substitution influence its reactivity. In order to investigate iron-aluminum solid solution in C4A3s, the following bulk compositions were made, C4A3(1-x)F3xs, where x equals: 0.05, 0.07, 0.09, 0.11, 0.13, 0.15, 0.17 and 0.19. Qualitative X-ray diffraction analysis (XRD) of samples prepared revealed only partial iron-aluminum substitution at 1100 °C, the rest of the iron giving up minerals: magnetite (Fe3O4), ferrite phase (C2(A, F)) and srebrodolskite (C2F).
