In the present study, eight specimens of Reinforced concrete Geopolymer bubbled slab exposed to fire flame and tested under punching shear failure with dimensions (45*45*7 cm), steel armature (Ø3@25), plastic ball diameter (4 mm) and concrete cover (1.5 cm) and the use of two percentages of fiberglass (0.5% -1% ) and the variable temperatures were (150- 300- 450 ˚C) with a burning time of 30 minutes.
From the results of laboratory tests, when the Geopolymer reinforced concrete bubbled slexposed to high temperatures, it did not occur to spalling, and the reason for that is that Geopolymer concrete has the ability to resist heat due to the fact that it's main compounds are materials burned at high temperatures.
And also, it was noticed in examining a punching shear stress of the models with fibers (0.5% ) that the ultimate load increased by (4.5% ) for the model burned at a temperature of (150 ˚C) and a decrease in the ultimate load was (40% ) for the models burned at temperatures (300 ˚C) and a decrease in the ultimate load by (30% ) for the models burned at temperatures (450 ˚C).
Also, it was noticed in examining a punching shear stress of the models with fibers (1% ) that the ultimate load increased by (6% ) for the model burned at a temperature of (150 ˚C) and a decrease in the ultimate load was (36% ) for the models with temperatures (300 ˚C) and a decrease in the ultimate load by (27% ) for the models burned at temperatures (450 In the present study, eight specimens of Reinforced concrete Geopolymer bubbled slab exposed to fire flame and tested under punching shear failure with dimensions (45*45*7 cm), steel armature (Ø3@25), plastic ball diameter (4 mm) and concrete cover (1.5 cm) and the use of two percentages of fiberglass (0.5% -1% ) and the variable temperatures were (150- 300- 450 ˚C) with a burning time of 30 minutes.
