Does concrete need to be cured before putting travertine down?

Got some guys doing the back patio and they put concrete slab down a week ago and from what I can tell never sprayed it (I’m traveling for work). Always thought you needed to cure concrete? Plan is to put some travertine tile on top.

It’s been triple digits all week with no rain. Am I boned? Do I need to call the contractor? Is there some newfangled concrete mix that doesn’t need spraying?

What kind of spraying? Concrete should be good to go for travertine with a week setting up in this heat.

It typically needs to be wet for 12-24 hours after pouring. At least that’s how I understand it to be.

Spray what? A sealer? Spray water on it for a slower cure? Concrete is cured enough in 7 days to drive a truck on it, so you are good to put travertine.

Spraying (misting is a better term to use) is not necessary though it does help to control the curing process and minimize brittleness. If you are going to mist, that basically has to be you doing it, the contractor isn't going to show up at your house 5-10 times a day to do that.

It's a patio, so I am guessing it will only get foot traffic and nothing heavier than a BBQ pit and maybe a golf cart/lawn mower type item. But since you are putting down travertine, I doubt a mower or golf cart are gonna be on it. So you probably have few worries here. 7 days in you are at 70% strength, so putting travertine down is perfectly fine. 30 days of curing will give you full strength, and that will still happen with the travertine on it.

You can, but he is going to be really really quiet after you ask your question.

Should have just add marble to the surface and grind it down and polish like terrazzo

If I was having concrete poured in 95 F temperatures, I would put water on the dirt to soak it before the concrete is poured and keep the concrete wet all day for at least the first several days. Concrete needs to cure slowly, not baked in the summer sun. Fast curing will cause cracking and weaken the concrete.

I don't remember just how fast concrete cures.... 70% strength after 7 days could be correct, but I would guess a lower number. After a month concrete is not 100% cured. Concrete continues to strengthen for years and years. Ask a concrete contract if he charges the same or more to remove 1 year old or 40 year old concrete slab.

Had expanded our driveway and the concrete guy said to wet it for 4-5 days to help cure it. I used an oscillating sprinkler about an hour each day.
