Concrete which affected with high temperature will lost its strength significantly by 60%. To overcome this problem is utilizing steel industry waste, that is Ground Granulated Blast Furnace Slag (GGBFS) which is used as a substitute for cement in concrete mixtures. The properties of GGBFS which is cementitious same as cement, so that it can fulfil the function of cement. In this research, GGBFS concrete and normal concrete with strength of concrete is 30 Mpa and both types of concrete will be burned at a temperature of 600°C for 2 hours. After that, characteristics strength of concrete will be tested to GGBFS concrete and normal concrete in each concrete before being burned and after being burned. The result of this research, there was an insignificant increase in strength of concrete with GGBFS as a substitute for cement by 40%. The average compressive strength of GGBFS concrete before and after being burned was 30.48 MPa and 11.16 MPa, compared to normal concrete which was 30.06 MPa and 9.76 MPa. Increasing also happened at the result of flexural test, wich is initial crack at GGBFS concrete occur in greater deflection and load than normal concrete.
