The energy consumption and the greenhouse gases emission in order to manufacture Portland cement (PC) is very high. To find an alternative, the researchers initially replace the PC partially by Fly Ash. Later on, the researchers introduce a new binder which is being manufactured by the activation of ground granulated blast furnace slag (GGBFS). The paper presents the detail of the binder, manufactured by GGBFS and mild alkali as activator having the pH value of 10. The binder is manufactured by simple blending in which 85% is GGBFS, and 15% is the chemical activator. The test results of the alkali activated binder concrete (AABC) for compressive strength, splitting-tensile strength and flexural strength were found after exposure to elevated temperature 100 °C, 200 °C, 300 °C, 400 °C, 500 °C, 600 °C, 700 °C and 800 °C. It has been observed that these results of the AABC at elevated temperature were very much comparable with that of the ordinary Portland cement concrete (OPCC). The deterioration in strength starts from 200 °C onwards. No spalling of the alkali activated binder concrete (AABC) has been observed at elevated temperature even at 800 °C.
