New materials used for the construction of structures or building components must meet strict construction requirements. Knowledge regarding the fatigue resistance of materials plays a key role during the design and maintenance of civil engineering structures. Previous work by the research team behind this paper deals with selected alkali-activated aluminosilicate (AAAS) composites based on ceramic precursors in terms of their characterization by mechanical fracture parameters, the approximation of their strength evolution over time, and the identification of selected mechanical fracture parameters using artificial neural networks and the comparison of measured load–displacement diagrams with those from simulations in ATENA FEM software. The presented contribution complements a set of mechanical fracture properties of a selected AAAS material via the determination of fatigue properties.
