Cold-Weather Shotcreting - boulderscape.com

ACI 306R-10 defines cold weather as: “Cold weather exists when the air tempera-ture has fallen to, or is expected to fall below 40°F (4°C) during the protection period. The protection period is defined as the time required to prevent concrete from being affected by exposure to cold weather.” Concrete placed during cold weather will

Protecting Shotcrete from Freezing| Concrete Construction ...

A.: Although shotcrete typically has a higher heat of hydration because of its higher cement content, the fact that it is placed in thin layers usually offsets the heat of hydration benefits in cold weather. Therefore, protection requirements for shotcrete in cold weather are generally the same as those for normal concrete. According to ACI 506, "Guide to Shotcrete," a minimum strength of 500 psi is required to protect shotcrete from freezing the same as that required for normal concrete.
