HomeMade Modern DIY Concrete Fire Pit
Quikrete 5000 (20-25 Bags)
QUIKRETE® 5000 Concrete Mix is a commercial-grade blend of stone or gravel, sand, and cement and is specially designed for higher early strength. This is the recommended concrete mix to use because of the high early strength and low price. It’s great for making tables, pavers, stools, and lamps and is typically found in 80-pound bags at Home Depot, but 60-pound bags are also available.
I used fire bricks from a local masonry supply yard. They aren’t the prettiest looking, but after a few fires they will turn black from the soot. Fire bricks are heat-resistant and will protect the concrete from cracking.
I mixed my own mortar from a combination of Portland cement, mortar clay and sand. I followed the directions that came on the mortar clay bag.
I bought pre-cut rebar in 12″ and 36″ sections. I should’ve purchased 18″ long sections for the verticals. I recommend using a combination of pre-cut 3/8″ diameter rebar. Use 18″ long pieces for the verticals and 36″ long pieces for the horizontal pieces. Make sure you drive the vertical pieces through the gravel and into the ground so that the ends are at least 3.5″ below the top of the wood forms. Wire the horizontal pieces to the vertical pieces so that the horizontal pieces will be embedded in each layer of concrete. This rebar frame will keep the different layers of concrete securely bonded to each other.
Quikrete 3/4″ Gravel
I used about 7 bags of Quikrete 3/4″ gravel for the foundation layer.
Iused two 5 gallon buckets full of lava rock that I purchased from the masonry supply yard. The lava rock is heat-resistant and won’t crack or shatter.
FOR THE FORMWORK:
2x4s + 2x6s
I used 2x4s and 2x6s held together with 2.5″ deck screws to make the panels for the formwork.
Iused L-brackets to join the panels at the corners. I recommend 6″ L-brackets.
