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

Abstract:

The mechanical properties of C40 ordinary concrete after different temperature and time were experimentally researched. A detailed review of experimental phenomena and the influence of the significant parameters were given, and the relationship between the compressive strength and temperature and time were discussed. The experiment showed that with the exposure of temperature and time increasing, the concrete cubic compressive strength tends to decrease generally. According to the experiment results, the formula for strength-temperature-time relationship after the fire was built. According to the coupling effects of temperature and time to the compressive strength, a new fire size classification standard was established.
