Hot Weather Concrete


Concrete in hot weather is subject to high loss of moisture by evaporation and rapid hardening, which affect the placement operations and the cracking potential. High ambient temperature, high concrete temperature, low relative humidity, and high wind speed are conditions that tend to damage the freshly mixed or hardened concrete. These circumstances lead to acceleration of the rate of moisture loss and cement hydration. There is no single maximum ambient or concrete temperature, but generally for the best results, a concrete temperature of between approximately 75 and 100°F (24 and 38°C) is considered most favorable for best results.
