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.

Shotcrete, a.k.a gunite, is a wet mix technique that produces a high velocity cone-shaped spray pattern via pneumatic mechanism onto a horizontal or vertical surface. Increase the air from the shotcrete nozzle to increase the velocity and the compaction of the particles and produce a denser concrete. Shotcrete uses either aggregates or mortar.
