Influences of Temperature and Time on Concrete Compressive Strength after Water Cooling

Abstract:

The concrete residual compressive strength after different burning temperature and time by water cooling was experimentally studied. A detailed review of experimental phenomena in fire and the concrete failure characteristics in compressive test were given, and the relationship between the compressive strength and temperature, time were discussed. It is found that with the exposure of temperature and time increasing, the concrete residual compressive strength tends to decrease generally, but when the temperature is low or time is short, the concrete residual compressive strength tends to increase on the contrary. According to analysis of the experiment results, the formula for concrete residual compressive strength and temperature-time relationship after the fire was built.
