The connection between eco and building materials can be successfully accomplished by using geopolymers. Geopolymers are composite materials made of long chain molecules incurred by polymerization of geopolymer binders. Usually, geopolymers are defined as a solid and stabile aluminosilicate materials, made of industrial byproducts and liquid solutions such as NaOH and Na2SiO2. …The experimental part of the dissertation, contains the results of physical-mechanical, microscopic and durability properties of geopolymer mortars and concrete based on fly ash. For the purpose of determining the effect of different byproducts on characteristics of geopolymer mixtures, 24 batches of mortar and 8 batches of concrete were made and tested. Mass percentages of ladle slag, wood ash, red mud and waste glass in respect to the total mass of the binder was 0 to 20%, varied in 5 % steps of replacement. Mass percentage of ground granulated blast furnace slag in respect to the total mass of the binder was ...0 to 100%, varied in steps of 20 % steps of replacement. All batches were made by using binder with the particle size smaller than 0,09 mm. The samples of geopolymer mortar and concrete were cured at an ambient temperature. …According to the test results some recommendations for the possible application of fly ash and other industrial byproducts for making geopolymer mortars and concretes are made. It has been proved that geopolymer mortars and concretes might be used as a construction building materials. Furthermore, because of their physical-mechanical characteristics and durability properties, they can be alternative solution for the traditional mortar and concrete mixtures.
