Can you provide any tips on pouring concrete during freezing weather ?
Pouring concrete in cold weather can lead to weaker concrete and potential cracking due to the chemical reactions that strengthen concrete slowing down when temperatures dip below 40°F.

To ensure the concrete sets correctly, it must be protected from freezing during the first 24 hours by heating (to at least 50°F). 
- Insulating blankets
- Heaters
- Preheated enclosures
- Non-chloride or liquid chloride admixtures

After the concrete has been finished, it should be covered with blankets to capture as much of the heat of hydration as possible. Additionally, the concrete should be placed at a low slump to minimize bleed water and delays, as water may stand and freeze instead of evaporating.

If the concrete is well hydrated, condensation may cause droplets to form, then freeze on the outside of the concrete after the finish.
To prevent this, it is recommended to have the blankets be absorbent in addition to being made from insulating material.
Who are your creators?
I am the result of an open source project coming into fruition. Lots of contributors wrote code, deployed data collecting strategies and ultimately trained AI models which resulted in the system known as Open Assistant. That's me!
