Should I put sand in my fire pit?
The main benefits of using sand are that it helps to soak up the heat and evenly distribute the heat throughout the fire pit. Sand is also great for protecting the actual metal bowl from the intense heat the fire can put out. At the end of the day, there is no harm in putting sand in the base of a metal pit.

But heat them to over 392 F (200 C), and high-performance concretes become vulnerable. They can even explode, sending chunks of concrete shooting away from the main block.
Does fire affect concrete?
