Abstract:

Concrete is widely used as construction material because it’s high durability and fire resistance. When any structures exposed to fire, its room temperature will raise continually, which cause deterioration of concrete structures. During high temperatures concrete loss it structural capacity and it may require strengthen and rehabilitations. This paper is an efforts to investigate the effect of elevated temperature on conventional concrete and concrete with granulated blast furnace slag( GBFS) as partial replacement of fine aggregate in proportions of 20%, 40 % and 60 % and 1 % steel fibers. The strength parameter was determine and compared with conventional concrete at controlled elevated temperatures like 200°C, 400°C, 600°C, 800°C, 1000°C for 0.5 hour, 1 hour and 1.5 hour constant heating and tested after 1.0 hours of natural cooling. This experimentation shown the strength of concrete with GBFS 40 performs well at all elevated temperatures as compared with conventional concrete.
