Thin layer cracking and flaking on new concrete

Post by gobfrey »

I just had a large concrete pad poured in my garden. It was mixed and pumped yesterday morning to the back of the garden. There's now a thin layer of light grey on top that's cracking and flaking. It's a bit thicker than a good coat of paint. Beneath it's darker and seem solid. I sent pictures to my builder and he says it's normal. Is he right?

Thanks

I'm no expert on concrete, but I'd suspect that it may have been over tamped which has brought what's known as the *fat* to the top (basically, the actual cement dust) and that is what is laying on top and cracking.
One day it will all be firewood.
