The object of the study is auxetic cementitious composites (ACC), considered with respect to their structural features, testing methods, and applicability in construction. This work aims to classify and analyse existing testing methods for ACC, evaluate their mechanical and thermophysical characteristics compared with conventional cementitious materials, and assess their potential applications in construction practice. Method. This study uses a general scientific method of information synthesis and analysis. Results. The results systematically analyse ACC test methods and their application in construction, including compression and energy absorption, bending, shear, cyclic and dynamic loading, thermophysical, explosion, and impact tests. The analysis indicates that ACC exhibits higher compressive ductility, energy absorption capacity, and resistance to cyclic and dynamic loading than conventional cementitious materials, and that their application options range from protective panels to damping and facade elements. At the same time, sensitivity to geometric deviations during production, specific lattice degradation mechanisms, and the lack of standardised test procedures limit the technology's practical implementation in the construction industry.
