Hello,
yesterday the concrete slab was poured at our site.
However, it’s been raining for the past few days.
What does this mean for the fresh concrete slab?
The mason laid a plastic sheet over the fresh concrete. Are there any negative effects from this? Doesn’t concrete need to be able to breathe?

first of all, welcome to the forum.
I’m certainly not an expert, but generally speaking, that’s quite little information for a fairly complex topic.
On the other hand, this question isn’t so uncommon that it couldn’t be answered by searching the internet.
The way you ask the question (and your age) makes me think you might not have much experience with house construction.
Are you building with a general contractor (GC), construction manager, turnkey builder, or architect? Don’t you have an independent building inspector or expert involved?
I mean, if you’re already worried now, how are you going to manage the coming weeks and months? The forum can help, but it can’t provide free construction supervision or competent quality control.
Now, back to your question and a bit of encouragement to understand the topic of house building for yourself.
Why does a concrete slab need to “breathe”? Why should a house “breathe” at all? It doesn’t even have lungs. What is concrete made of? And what happens if one of these components (in this case water) is present in too large an amount? And what could be the purpose of a plastic sheet? Oh, and also check if you can find information on concrete curing.

The mason placed a plastic sheet over the fresh concrete... Are there any side effects from this? Doesn’t concrete need to breathe? This is actually the best way to cure the concrete. It doesn’t cause any problems at all.
The plastic sheet is used to prevent the water from evaporating too quickly.
So everything is perfectly fine.
Concrete does not need to breathe; it is already inert.
The water in the concrete is not meant to evaporate but to hydrate; otherwise, cracks may occur. That’s why a covering film is usually placed on top.
Otherwise, concrete also cures underwater. Since heat is released during this process, cooling is actually beneficial. Expansion and thus cracks are avoided.
