Concrete slab craking 1

[72shortbox]

I read a lot of post discussing cracking in floors during the curing period.
Anyone have a short list of items/procedures which should be followed as the floors are poured, finished,joints installed, cured to prevent cracking. An Inspectors Checklist.

Lots of info in that thread.

Check with American Concrete Institute publications. You'll find current and credible information.

basford,
fndn is right. Further, ACI membership is inexpensive, and gets you a good discount on ACI publications. It's well worth it IMHO.

Sorry to comment, I didn't read that thread. Too much water in the concrete will cause honeycomb cracking, as is the case with my parent's front porch. Every time I cross those steps, I think, man if I was only there for that pour...

Cracking is an extensive topic and can be studied extensively. One thing I learned in my experience is that if the subgrade is uneven, cracking can occur. Uneven sections of concrete will react unevenly to a load, causing them to behave differently than the surrounding material. I was on a project where this was the cause attributed. Epoxy injection was used as the solution to these apparently wide cracks.

Best of luck.

You ever seen what hppens to a mud hole after it starts to dry?
yes the mud in the bottom dries up and cracks,same thing with concrete.
most important thing to do is keep the water in as long as you can,that and only that will stop major cracks.

so seal it ,spray it with water, or what ever it takes.
