Concrete Mixture Question - Forno Bravo Forum: The Wood-Fired Oven Community



New Forno Bravo Forum Feature

Forno Bravo Forum Community,

You will notice a new forum at the top of the main page called, "Ask Me Anything". This forum will be used for live one hour "Ask Me Anything" (AMA) sessions hosted by people who are knowledgeable in different areas pertaining to wood fired ovens. How it works:
- Each AMA will have a "sticky" thread where the community can post questions they would like answered during the live session. This will allow everyone to participate even if you can't be online for the live session. These questions will not be answered by the host until the live AMA; if you need an answer quickly, you should post it in the appropriate Forum area for the community to respond.
- Another thread will be posted for the live AMA. Registered users who are logged in during the live session can interact with the host by asking questions and receiving responses.
- The live thread will remain in the AMA forum to view after the session.

To kick off our AMA feature, we have invited author, chef and master bread maker and host of Pizza Quest, Peter Reinhart, to be our first host! Peter will be in the Forum on Monday, February 15th, from 7:00 - 8:00 pm EST. If you are unable to be online during the live session, you can post your questions in the sticky post. Peter will answer those questions during the live session on February 15th. You can view Peter's answers to your questions as well as what happened during the live session in the session thread.

We hope you enjoy this new feature! Please let us know if there is a topic that you'd like to have as an AMA and we'll look for a host!

  • Concrete Mixture Question

    I am trying to decide on a concrete mixture for a decorative band which separates the different levels of the enclosure. I'll be forming one pour on top of the cinderblock, then using metal framing from the top of the band up to the top of the enclosure. Manufactured stone will be veneered to the enclosure. I made 2 test forms for the pour I want to do. The first was bagged concrete, the second was 3/4 part portland, 1 part sand, 2 parts vermiculite. The concrete one weighed 34 lbs., the other 22.5 lbs. Does anyone know if it's worth it to do the lightweight concrete given the metal framing and the upper enclosure weight will be sitting on it?

    Are you going to veneer over the band? If so, why bother with it? If not, it's a question of aesthetics--which looks better to you?

    If weight is the concern, how about modifying your form to make the casting a "donut" rather than a solid? Maybe throw in some reinforcing needles or fiberglass strands if you're worried about how it will hold up. The steel stud bottom plate can span a 6 or 8 inch hole. Just support it where the plate anchors and vertical studs are located by filling the cavity with concrete (you have to do that anyway). That'll drop a bunch of weight; the casting probably won't weigh more than the cinder block.

      I would avoid a vermiculite/cement mix in any exposed area. It is subject to damage and is not water resistant at all.

        Thanks for the suggestions. The picture below is the look I'm going for. The decorative band at the top is the one I'm concerned of, as far as weight I suppose regular concrete is the way to go. Thanks again for the replies.
