Stone/Masonry fire pit project - Need Advice
I am looking to build a fire pit. I am wondering what type of construction material is best suited for this. What I have been looking at are concrete bricks, building bricks (made from dirt, sand, water) and stone bricks.
I know the cheapest is concrete bricks however my son has seen concrete ones (blocks) explode when they got hot from being near a fire. I do not know if this is unusual or if they are just not made for this type of heat.
The next step up is building bricks (the typical RED ones), but they are small and it would require a lot to build up the pit.
The third choice is the stone bricks. These are great looking and have a lot of choices, however they are the most expensive.
The stones that I have seen are granite, flagstone, limestone.
I am looking for something that is durable and not cost too much money.
Any suggestions?

Stone is the best option, it doesn't heat up. Many firepits have a metal drum buried into the ground with bricks on the outside of it.

spalling of concrete is possible when trapped moisture is heated and converted to steam .... I do not know how common it would be for concrete pavers/bricks to explode, but there is the potential for them to crack and come apart, how violently is anyone's guess could always purchase a metal fire pit

here are some samples of DIY fire pits, and yes I agree with Kevin, stone would be the best choice even if it is the more expensive way of doing it ...... notice the saying on my signature

Good luck!

ty for the reply!
The pictures give me some good ideas to work with.
I already have a metal fire pit. It is quite small.
I am looking for something @2x that size.

Make sure you check code to see what you are allowed in terms of BTUs and at what proximity to your home. Some communities are enforcing more and more strict regs on woodburning too so you might want to run a line for gas adaptation for future use when building this.

Some Ideas about Fire Pits
Thought I need to share my recent blog site and perhaps it might help.

I have built one three years ago up on top of a mountain on my property. It was made simply from river rock...its free and its from nature.

It is still standing and in use so...its a thought
