for a do-over.
That experience stuck with me; it taught me the importance of doing it right the first time, especially in cold weather, when even small mistakes can turn into major setbacks. If you’ re in the same boat( pouring concrete in winter conditions), I’ ve got some best practices to share.
Let’ s dig into what you need to know to make a winter pour successful.
Understanding Concrete Behavior in Low Temperatures
When temperatures dip below 40 degrees Fahrenheit( or 4 degrees Celsius), the hydration process slows down. Hydration is what allows concrete to cure and gain strength, so if it’ s not happening the right way, your concrete may not develop the durability you’ re expecting.
The real danger comes when the concrete temperature falls below freezing( 32 degrees Fahrenheit or 0 degrees Celsius). Concrete should always be cured before it is allowed to freeze, otherwise, water in the mix can freeze, causing expansion that leads to cracks and structural weaknesses. If you’ ve ever seen a sidewalk or driveway riddled with spidery cracks, there’ s a good chance cold weather played a role in its early life.
In short, concrete in cold
