dc.description.abstractThis paper investigates the residual compressive strength and ultrasonic pulse velocity (UPV) of concrete, which has been water-cured after exposure to high temperatures. The relationship between the residual strength ratio and the residual UPV ratio was developed. Cylindrical specimens were made of concrete with water-cement ratios of 0.58 and 0.68 and, after 90 days, the specimens were heated in an electric furnace to temperatures ranging from 400 to 1000 degrees C. The concrete specimens exposed to elevated temperatures were cured in a water tank for 72 h and tested after 4, 27, 87 and 177 days. The ultrasonic pulse velocity and compressive strength of each post-fire-curing specimen were measured. Experimental results show that water curing of the concrete specimens after exposure to high temperatures has noticeable effects on the residual strength and UPV recovery. It is also shown that a change in the mixture proportion of concrete does not have a significant effect on the residual strength ratio and the residual UPV ratio of concrete subjected to elevated temperatures. The relationship between the residual strength ratio and the residual UPV ratio was developed and a general equation is proposed for predicting the residual strength of post-fire-curing concrete. Finally, this paper verifies the validity of the proposed equation for predicting the residual strength ratios of post-fire-curing concrete with the measured residual UPV ratios.
