We are aware that the physical and mechanical properties of concrete can be greatly altered by extreme climatic conditions during construction. As winter approaches, it's time to remind everyone of the few precautions and good preventive practices that allow you to continue building with complete peace of mind when the rigors of the cold strike. The consequences of the cold on the concrete: beware danger! Concreting in cold weather, when the temperature drops below 5°C, becomes more complex.

At a temperature below 0°C, the mixing water present in the fresh concrete freezes. This phenomenon generates the dilation of the wa
