The aggregates will heat up and expand and might potentially pop or explode. I assert that all fire pits should be lined with fire brick and fire clay mortar.

Will concrete crack under heat?

Severe heating or cooling can expand or contract the concrete, respectively. When heated, the concrete develops potential and compressive stress, resulting in the structure’s thermal cracking.

What is fire resistant concrete?

Definition: (1) the property of a material or assembly to withstand fire or give protection from it; (2) the ability of building elements to confine a fire or, when exposed to fire, to continue to perform a given structural function, or both.- ACI Concrete Terminology.
