It’s also incredibly resistant to fire, which makes it a safe bet for homes. The fire-resistant properties of concrete are fairly easy to understand.
Will concrete crack under heat?
When heated, the concrete develops potential and compressive stress, resulting in the structure’s thermal cracking. Thermal cracking could also occur if the temperatures of different portions within the same concrete slab exceed a specific limit.

How thick does concrete need to be to not crack?
To prevent load-stress cracking, make sure a slab is built over a uniformly compacted, well-drained subgrade, and is thick enough to withstand the kind of use it will get. In residential concrete, 4 inches is the minimum thickness for walkways and patios.
Are concrete pavers safe for fire pit?
The inner wall must be made of fireproof building materials, optimally fire brick; the outer walls should still be heat-resistant but can be made of traditional brick, stone, masonry blocks (consisting of brick, concrete, granite, etc.), concrete pavers, or even heat-resistant outdoor stucco or tile.
