In this regard, in recent decades, high-strength concrete in order to excel mechanical properties and durability and eliminate environmental disadvantages (due to the production of toxic carbon dioxide) in ordinary concrete, has been considered by civil engineering researchers. In this laboratory study, a mixing plan was made of ordinary concrete containing Portland cement with a grade of 500 kg/m3 and a mixing plan was made of alkaline concrete based on slag from a composing furnace. In order to evaluate the mechanical properties and durability, compressive strength and weight reduction tests of concrete were performed at 21 and 600 °C at a 90-day curing age in concrete. Applying high heat in concrete samples caused a decrease in the results of compressive strength test in ordinary concrete and reinforced concrete by 42.31% and 14.9%, respectively, and in weight loss test by 0.0067 and 0.0064%, respectively. Weight loss was achieved in ordinary concrete and alkaline concrete. Alkaline reinforced concrete in the compressive strength test at 21 and 600 degrees Celsius, showed an advantage of 11.41 and 64.35 percent compared to ordinary concrete. The results of scanning electron microscopy imaging test were in coordination with the results of other tests in this study. Manuscript profile
