It's all about the water. If the amount of water added to the batch in order to keep it usable exceeded the mix design's w/c ratio then it won't produce the specified mix - period. If there's too much water then you didn't install the specified mix.

Besides, there is Already a building on it so it would be very difficult to send back now.

Re: How Do You Know When Concrete Was Too Hot To Pour


Evidence of what? Mud was 2 hours old ?
What do you suppose is going to happen?
I got info from a special inspector that doesn't seem to be too concerned about it. As a matter of fact he said 4500 psi isn't for the load, it for the acidic soil and the 4500 is needed for its density. But the slab has 4 inches of sand and plastic so the concrete isn't even contacting the soil. The footings were poured with the first truck that had no problems.

I don't think ANYTHING bad is gonna happen. In fact, I thought all of this was much ado about nothing.

Here we are, still talking about drum turns & water ratios and the durned building is nearly done!

A builder here had a 5,500 sq ft poured an hour and fifteen from the plant in august. Last truck was a 11 am, probably 100 degrees. Had a structural crack that the client sued for, and won.

Not a lesson to forget

That contractor must of had a piss poor lawyer because 90 minutes is acceptable practices, so if it was 75 minutes old he was within acceptable time limits, so something tells me there's more to the story then 75 minute mud.

Good lawyer, the client was a better one The client was a prominent litigator and a college football star. Story is he told the builder he should of known hed sue for something.

I dont know the whole story, the guy may of set up his slab improperly.

My post had nothing to do with your thread, Im sure your slab is fine.

Usually structural cracks are soils related, if its poured on expansive clay and the ground was dry there can be extensive structural cracks, expansive clay can exert as much as 15000 psf. Usually following a rain or irrigation. The way that is solved is to saturate the clay before you pour so the soil is pre expanded. This has to be accompanied by a structural slab that has been engineered with the proper reinforcement.

May be a contributing factor...but

Mix design as ordered compared to what was delivered...

or how it was placed

Water/Cement ratio

add mixes or lack of

Weather

over worked mix

How was it cured?

when was it saw cut?

I'm sure there's more...but I can't recall any right now

Re: How Do You Know When Concrete Was Too Hot To Pour


Lots of things that go on that we have no control over, like non of us get to see them actually mix it. Other things we can't control is the weather. But your right Griz, many factors when it comes to concrete, most of those factors are above my pay grade. ( like engineering )However, I try to keep up the quality on the things I can control.
