Original Abstract

The research is focused on the possibility of maximum utilization of FBC fly ash in AAC technology and its impact on the properties of the AAC. In the research, the FBC fly ash was used as a partial substitute for binder components in the AAC formulation. The amount of FBC fly ash substitution was chosen on a scale from 10% to 100%. Physical-mechanical properties, such as compressive strength and bulk density, were performed on samples of autoclaved aerated concrete. Compressive strength was approximately constant up to the 50% FBC fly ash substitution. XRD (X-ray diffraction) analysis, SEM (Scanning electron microscope) and EDX (Energy Dispersive X-ray) analysis were performed to identify the formation of tobermorite. EDX microstructural tests have confirmed the incorporation of aluminum ions into the crystalline CSH. Further, an amount of crystalline tobermorite in the samples was approximately constant up to 50% of the FBC substitution. The results are shown that the maximum FBC fly ash substitution is possible up to 50%.
