Course Summary

Placing of concrete during cold weather has the potential to effect both the long term strength and durability of concrete. Cold weather can have a negative impact on both plastic and hardened state of concrete. Cold weather affects most of the major components of concrete including water and aggregates. Cold 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 affected by cold weather.
