Placing of concrete during hot weather has the potential to effect both the long term strength and durability of concrete. Hot weather can have a negative impact on both plastic and hardened state of concrete. Hot weather effects all of the major components of concrete including water, cement and aggregates. Hot weather also has an impact on batching, mixing and placing of concrete. Precautions must be taken in advance of concreting operations that are anticipated to be effected by hot weather.
