The research deals with the possibility of maximum utilization of FBC fly ash in AAC technology and its impact on the properties of AAC. In the research, fly ash was used as a partial substitute for binder components in the AAC formulation. The amount of fly ash substitution was chosen on a scale of 10 % to 100 %. Physical-mechanical properties such as compressive strength and bulk density were determined on autoclaved samples. XRD analysis, SEM/EDX analysis were performed. Using these analyses, the change in the microstructure of autoclaved aerated concrete was monitored with increasing amount of FBC fly ash used. EDX microstructural tests have confirmed the incorporation of aluminum ions into the crystalline CSH. Further, an amount of crystalline tobermorite in the samples was observed which was almost constant up to 50 % of the FBC substitution. Compressive strength also began to decline significantly when the 50 % FBC fly ash substitution threshold was exceeded. The results thus show that the maximum FBC fly ash substitution is possible up to 50 %.
