Abstract
This paper presents an experimental investigation of the effect of fire flame on self-compacting concrete. The experimental program included casting cylinder and prism concrete specimens for compressive strength, modulus of elasticity, modulus of rupture, and concrete density tests. The specimens are exposed to fire flame at 800 ºC approximately for 2 hours or 6 hours. Then the specimens were cooled either in a fast or slow manner. Test results show that the compressive strength was reduced by about (54 - 61)% for fire exposure of 6 hours and by (27 - 37)% for 2 hours of exposure and cooled slowly or fast, respectively. The type of cooling affects the percentage of reduction in compressive strength. Fast cooling reduces compressive strength more than slow cooling. The influence of fire flame on elastic modulus is more pronounced than on compressive strength. The modulus of rupture was reduced by 13% and 20% upon exposure to fire for 2 hours and 6 hours, respectively compared to the unburned specimens. The non-destructive test by Ultrasonic Pulse Velocity (UPV) tool is acceptable to assess the compressive strength of concrete after exposure to fire, whereas the Schmidt hammer test was found inaccurate for the assessment of compressive strength after fire exposure
