Any concrete experts in here? Or contractors that are familiar enough with concrete?

[QUOTE="black4vcobra, post: 14445288, member: 82394"] I assume that is the finished concrete and they didn't put any sort of a sealant on it, correct? Clearly they screwed up on the finish. Interior concrete finishing involves "fan type" power float and it has to happen after hydration (hardening) starts but before it's too far along. It takes more skill than a brush finish for outside concrete. Is it a reputable contractor that performed the work? 6000 psi compressive strength would be ridiculous for a slab, it's probably 4000 psi which is still an upgrade over what you would normally see for a slab. It might be helpful to get a mix design from the contractor or ready mix company and see what the aggregate size is and if they put any ad mixtures in it. [/QUOTE]
