I've had a concrete patio laid on Mon and today It is still not set (its like toffee) Is this normal?

Its an impressed concrete patio,some of the edges of the pattern look like there are cracks appearing as well, I’m worried of the long term effects of this.
Just an update, The men have turned up this morning and started to wash off the surface with my garden hose and the concrete is coming up with just the hose pressure,they’re now going to dig the lot up and start again!!
update
The cement supplier has been out and over a ton of cement was missing from the mix going by the readings when mixed. Everyone has been great so far but the work has to start from scratch.

  1. no not at all
    general twenty four to 48hrs it should be set

  2. No, not usual, did it freeze overnight or even get down to 0 while it was setting? If it did you could be looking at relaying it.

  3. contact the people who poured the concrete, your may need to have them do some repairs to get it to set better.could be the weather is hindering it from setting up.

  4. just goes to show ..not every body`s a cowboy who you never see again

  5. Tell them to put cement in it this time looks like the first attempt did not have enough in there.

  6. They must have got their proportions wrong when mixing the concrete, I always ensure my concrete is mixed to the set proportions and I have not had a customer complaint yet.
