Concrete slab

[Faz786]

Hi all,
I had concrete slab poured on two ends of the garden. One for my kitchen extension (which was poured in first, please see 3rd image) and one at the rear end of the garden for a shed . The concrete slab at the rear end of the garden is showing signs of flaking quite a bit (this is the next day) . The concrete poured for the kitchen extension is completely fine. I am assuming that it is flaking because maybe more water was added towards the end or due to exposure to the sun . What shall I do or is there a way of rectifying it?

That went in very wet and has bled badly. Very doubtful if any attempt was made to cure. Typical of DGAS builders I fear.

The concrete will be a bit weaker than it should be because it has less cement remaining in the matrix. Nothing you can do about it now but for a shed it's not likely to be too big an issue.

Thanks for the feedback.

I don't see an issue with either unless the concrete is on show. A fascia slab is usually poured with a minimum of C30 and float finished. Otherwise it's tamped and left well alone. A flaking surface is not going to be an issue.
