One of the most important factors that cause global warming and climate change is the emission of CO2 into the atmosphere. A significant amount of the emission of this gas (6-8%) is derived from the production of cement, the most used building material in the world. For twenty years, in order to reduce this amount, researchers have been working intensely on geopolymers, a sustainable binding material alternative to cement. Geopolymers, waste side-products of flying ashes, high oven curve, etc. A source of aluminium-silicate and NaOH, Na2SiO3 etc. It is made up of activators. As a source of aluminum silicate, volcanic ashes containing amorphic SiO2 and Al2O3 are formed, flushed, pumped, etc. It is used in mineral materials. In this study, the production of geopolymers from perlitten found in significant amounts in the Erzurum Pasinler region and containing aluminum silicate has been studied. The perlit provided for this purpose is used as binding and geopolimer concrete is produced. The mixture used only NaOH as an alkaline activator and, as a result of preliminary experiments on the produced samples, 72 hours of thermal curve was applied at 90°C. The water absorption rates of the produced samples, unit volume weights and 3, 7, 28 and 150 day pressure resistance have been detected. The samples were also exposed to 5% concentration HCl and MgSO4 solutions, 50 circular freezing-solving effects and 300°C, 500°C and 700°C high temperatures. The tests ended with the mechanical and physical characteristics of the samples. As a result, the pressure resistance of 20.50 MPa was obtained by using NaOH alone as an activator in perlit-based geopolimer production. In terms of durability, it has shown good performance compared to the normal Portland cemented concrete with the same durability.
