Description
One of the major causes of structural repairs worldwide is the corrosion of reinforced
concrete structures, such as residential buildings and piers, which are exposed to harsh
marine environments. This investigation aims to provide experimental evidence of the
fire resistance of corroded high strength reinforced concrete. For this, 14 reinforced
concrete beams of three different concrete mix designs (different strengths) were
prepared along with concrete cylinders for compression strength testing (ASTM C39).
After proper moist curing, all beams were corroded, in two phases, with impressed
current, then “crack scored ”for corrosion evaluation, after which half were exposed to
fire, also in two phases, following the ASTM E-119-12 time-temperature curve, using a
gas kiln. The fire damage was evaluated and compared between phases by using
Ultrasonic Pulse Velocity technology. Finally, all specimens were tested for flexural strength by using the third-point loading method (ASTM C78) and the effects of fire on the corroded beams were analyzed according to the level of corrosion.
