Great spatchcock chicken and a Horrible accident

Options
This was my first time doing spatchcock chicken. followed some advice on the Forum like leaving the chicken sit in the fridge for 12 hours to help crisp the skin which works awesome We used olive oil  and Dizzy Pig tsunami spin. Cooked the brest till 172 then pulled. I never Ftc after so the skinn would stay crispy  The egg dome temp was 375ish. Ps in legs up, ss grill on legs. 
Ok now for the accident. 
I had my chimney with my lump getting hot sitting on my cement when it blew up. Lump went everywhere and there is a brand new hole in my cement that the wife is not happy about

    I do not have the XL in the table yet so it was under my patio and me and my buddy picked it up and had just set it down when it went off 15 seconds prior we would have been holding the XL and might have dropped it when it's scared the crap out of us

    Sorry I'm new (and confused) to exploding concrete. Can anyone enlighten me on how this happens? Google search doesn't bring back much either.

    I've seen concrete damage from high heat before, but not to that extent.  Was the concrete wet?

    Any road will take you there if you don't know where you're going.

    I was thinking the same thing. Maybe poured within the last week.

    This was recently discussed in a recent thread ( started by @Judy Mayberry , I think).

    Water in the cement changes into steam and causes the cement to explode like that. So always set your chimney on a grill, or have something between the concrete and the chimney.

    Put a potted plant over that circle and chalk one up to experience.

    Learn something new every day. Spalling search brought back much better results than exploding concrete. So if you set the chimney on a concrete block could this still happen?

    Doesn't need to be "wet"

    needs to have any amount of moisture in it at all. And then 1200 degrees of heat placed on it instantly

    concrete is always damp. Even when it is dry

    Too bad about your concrete - chicken looks good though




    Wet isn't good in concrete or the jungle.

    I met a guy who loved fish tanks. He grew up very poor in India. He said when he was a kid he would get a fish and keep it in water in a pit in the concrete of his floor. 

    I think you should tell people that you always wanted an egg but before you got one you would BBQ in that little concrete pit. Put a little flower pot upside down on it to complete the story.

    Polish it up a bit with a grinder and you have a great resting place for a hot wok.

    Wowza!  I was thinking concrete counters for an Egg table would be great.  Not so much now.

    For years I did it on my grill grate.  No issues.  Then in a recent thread someone said they just do it down in the firebox inside the egg.  It was like a lightbulb went off...   light it where I'm going to dump it anyway.  Perfect!

    So now I do that.  Plus the pops and cracks have to travel a lot further to get out of the egg.  I like it.

    My question is why are you using that to start your charcoal? Just use an electric starter in the egg and you don't have that problem.

    Concrete will blister at high temps, especially in a chimney starter with lump. When I use one I sit it on red bricks or on the grate in the egg

    I use the chimney because prior to the big boom it worked great. I would sit it in the side burnner of the gasser and let it get hot then move to cement till it was all hot. Well not anymore. Lol i like the wok idea.

    @focker warned me about that recently. I always set my chimney on the driveway with no issues but won't be doing that anymore. Chicken looks good though.
