The development of geopolymers, as an alternative to traditional cement, by alkali activation of fly ash is a research topic in the scientific community. Many authors have agreed that there is a strong link between mechanical properties and microstructure of geopolymers. The aim of this study was to investigate the development of fly ash-based geopolymer microstructure at room temperature and to establish relationship with its mechanical properties. By scanning electron microscopy and microanalysis of geopolymer, a more detailed understanding of the geopolymer microstructure formation and development was achieved. It was established that significant changes of geopolymer microstructure occurred during the first 28 days of reaction at room temperature. After this initial period, less significant changes of fly ash based geopolymer microstructure were observed up to 180 days.
