Concrete types, reinforcement, etc

Hello ubarch,

You could use the "Hardazell" test to see if the concrete has cured.

Cheers,

I do not recommend that you Google that term.

Come spring, I plan to pile some 80lb concrete bags on top of it for a week or so to see if any cracks appear. I might buy a few refractory bricks, get a notion of the density, estimate the volume of the oven, then use those terms to get a rough picture of the oven's weight, and finally put 1.5x that estimated weight on the stand.

I seriously doubt you need to bother with that. I don't remember exactly what the numbers were but when I did the weight calculations for my oven the numbers were ridiculously low for the strength needed for the stand and slab.

LOL. I know what you mean I lsearched for it and got a lot more than I expected.

I think you are really worring too much about the slab. If you mixed the concrete according to the instructions on the bag and you put some reo in the slab you should have no problems. Has the slab hardened now? I.e. does it have a hard surface? can you take some photos of the surface?

To answer your questions:

1.) Yes, I followed the bag instructions exactly. I measured the amount of water in a plastic container, then marked the container so that mixing was consistent.

2.) There is a lot of rebar in the slab. According to advice on this forum, the slab should actually have a %1 grade to drain off water. I poured it so that it had a %1 grade. It's 3.5" thick on one side, and about 5" thick on the other. There is more rebar towards the thin side than the thick side.

3.) Sure I can take photos. I'm at work now, but I'll post some macro shots of the cement. It seems plenty hard, and it developed an almost white color after a day or so.
