Concrete is produced cement-bonded system, which is a composite material formed by the combination of different components. The hydration process of the cement and the hydration products affect the mechanical and technological properties of the concrete. In this sense, the curing process is needed to achieve the targeted mechanical properties. In this study, concrete samples were produced by using additives with different origins called mineral additives. The samples were subjected to pressurized steam curing with the help of autoclave at different temperature and pressure values. After the curing process, the compressive strength of the test samples were investigated. In addition, the cured samples were kept in high temperature furnaces at 450 and 900 0C for 6 hours and the compressive strength of the samples were examined. As a result of the study, it was found that the autoclave cure caused an increase in the compressive strength of the concrete at 400 0C. The best high temperature resistance values were determined in the blast furnace slag addition series.
