Pizza Oven Hearth Concrete Pour - Wood-Fired Oven - June 2024
Yesterday, I showed how I built a platform for the Mudmixer in order to pour the raised hearth in our backyard wood-fired oven stand construction project. Today, we show the details of the actual pour. Using the Mudmixer and 35-or-so 60# bags of 4K PSI concrete mix, I was able to complete the job in just about an hour of run-time. I spent quite a bit of time trying to make sure the forms were level and square and using a mix of sand (to fill cores), caulk and backer rod, I filled as many of the gaps in the forms as I could to keep the slab from leaking too much.
The good news - the forms held. They didn't bow. And...they didn't leak that much. Same with the supports under the Densshield boards. Below are a few photos showing the raised, reinforced hearth pour. The first one shows the platform and the poured hearth:
Below are a couple of shots showing how snug the Mudmixer was to the forms on the platform:

Once I remove the forms - I'll be done with the stand construction and can move on to the actual oven build. It has been quite a journey.
January 2024 - Location decision in our backyard.
January 2024 - Using LEGOs to decide on the size/spacing for the stand.
January 2024 - Excavation begins - to find the drywell.
February 2024 - Excavation continues to get the site ready.
March 2024 - Forms started for reinforced slab.
March 2024 - Adding gravel to site for drainage.
May 2024 - Rebar for slab bent and laid out.
May 2024 - Bought a 10" wet saw to cut the firebricks.
June 2024 - Cutting tile backer board for under the hearth.

That means, we're five months into this project. Excavation started in January. We're about to hit July. Wow. Next up - stripping the hearth forms to see how this pour went.
