Moveable Cement Firepit





Introduction: Moveable Cement Firepit

I made a concrete firepit in my backyard, in suburban America, to enjoy over the summer. I first made a mold to pour the concrete in out of 3/4" plywood that used to be part of my neighbor's floor. I cut a large octagon and smaller side pieces as walls and nailed them together. Any holes between the boards were patched with duct tape, trash bags, and cardboard.

I mixed portland cement with Quikrete all-purpose sand in roughly a 1-3 ratio and poured it into the mold. I used some chicken wire from the garage through the mold to try to give strength to the concrete.

The legs of the firepit are made from some aluminum pipe that was salvaged from our pool's solar cover, which had gotten torn up. There are four legs, two of them with wheels so that it can be moved. The wheels are salvaged from an old lawnmower I took apart, and were bolted onto the aluminum pipes.

Broken glass from beer and wine bottles was used as decoration along the top of the firepit.  I broke them by smashing the bottles inside a five gallon bucket with a sledge hammer.

I realize there aren't a ton, or very good pictures, but I figured someone may find some use out of this.

I like commments!! : )

Nice work! Did you calculate the size using some formula or was it just 'this looks good'? I'm thinking that if the walls weren't so thick it would be lighter & easier to move. Also, you've had it for a while now, how has it worked out over time?

There was some calculation involved, but mostly what looked good to me at the time. If I could do it over again I would have definitely made some big changes. Over time, it hasn't gotten a lot of use, and it has cracked more than we would have liked. Also, the broken glass may look nice, but my mom for whatever reason now sees it as a big safety hazard, even though I disagree.
So, for next time I would make the pit itself smaller, as we don't need one as large as this. The walls would be 2 inches thick maximum, instead of four. I would use refractory cement to reduce/eliminate cracking, and I would use glass beads instead of broken glass to avoid sharp edges.
Thanks for the comment!

ummmm...i didnt think high heat and cement were a good mixture???? air bubbles in the finished form could ((((POP))))

That is both true and untrue. The fire from the wood burning is unlikely to get hot to the point where a lot of cracking is an issue. However, using refractory cement is a much better option is you can find it.

right firepit (bowl) is all steel, and potable as hell. 1st meal was cooked in it, frm starting to cooking in about 45 min. though i started it months after i cut the tank in half (40 min job using a jig saw)...but portable concrete pit is an awesome feat.


Nifty idea you have. I admire your drive to build the fire pit even in suburbia!

What about general dimensions?
it's not very heavy?

I believe that it is about 4' by 4'. The walls are about 6" wide and 6"6 tall to the floor of the inside of the firepit. The total height is about 10" high. It is extremely heavy, with everything from the bags adding up to be a fair bit over 400 pounds.
