 Summary:
 This paper researched physical-mechanical characteristics of geopolymer mortar mixtures based on fly ash, with addition of waste aluminosilicate materials such as red mud, biomass ash, silica dust and waste ceramic tiles. Four mixtures are made with the same 90:10 ratio of mass of fly ash and other binders, while on one mixture is made with fly ash only. The quantities of other materials required for making of geopolymer mortars such as the quantity and type of aggregate, aluminosilicate activators and water are constant. All mixtures are cured in the same laboratory conditions, at the temperature of 95°C for 24 hours, and afterwards the specimens are cured at the temperature of 22°C until the testing. The goal of this research is determining how the same water/binder and binder/agreggate ratio affects the physicalmechanical characteristics of geopolymer mortar mixtures made of various waste materials.
