EVALUATION OF POST-FIRE RESIDUAL STRENGTHS OF IN-SITU CONCRETE AND STEEL REINFORCEMENTS SAMPLESUSING NON-DESTRUCTIVE AND DESTRUCTIVETEST METHODS.

The post-fire residual strengths of in-situ concrete and steel reinforcement samples were evaluated using non-destructive and destructive testing methods. Sixty samples of 320 mm x 150 mm x 100 mm reinforced concrete beams were cast in the laboratory in four batches of fifteen samples each with concrete cover for reinforcement varied at 10 mm, 15 mm, 20 mm and 25 mm respectively for each batch....
