What do you put under a fire pit?
Heat Shields
Regardless of the location of the fire pit, putting a heat shield under the pit will protect the surface from fire and heat damage. Heat shields are fairly portable and easy to use. No assembly is needed; simply place one under the fire pit on a flat surface, and light your fire without any worry.
How do you make concrete fire resistant?
Calcium Aluminate cement and Lime will work the best as the cement in hot cooking conditions- This applies to refractory concrete as well as to heat resistant mortars. (Lime is sometimes mixed into fire clays. This is mixed like a normal cement based mortar, but with half the cement replaced with the lime.
Does a fire pit need air holes?
The simple answer – All fire pits should have holes to permit airflow to the flames . Without oxygen flowing to the fire, it won’t burn much at all. So, for a lovely, bright, and safe flame, holes clear of debris are necessary.
Does cement 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.
What can I use instead of firebrick?

What is the maximum temperature concrete can withstand?
The threshold of significant degradation of concrete is around 65-93°C (150-200°F) . For this reason, current codes and industry standards dealing with reinforced concrete structures specify a maximum temperature limit of about 65-93°C (15O-2OO°F) to ensure predictable concrete behavior.
Whats the difference between cement and concrete?
What is the difference between cement and concrete? Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete . Concrete is a mixture of aggregates and paste. ... Cement comprises from 10 to 15 percent of the concrete mix, by volume.
How do you vent a fire pit?

To do this, place two vents on opposite sides of the fire pit to allow various exit points for heat and gas. Without multiple vents, gas can still get trapped on one side due to poor airflow.
What makes a good fire pit?
The materials that we see the most are stone, brick, concrete, stainless steel, and cast iron . These metals hold up well under high heat and are also rust resistant! For the standard fire pit, the most common fuel source is wood, but there are other options that use propane, natural gas, and charcoal.
