Steam Curing an Outdoor Pour
Steam Curing an Outdoor Pour
(OP)
I am in a project that requires the installation of new frames to support a piece of industrial equipment with a 3 day MAX turnaround. This includes demolition of the existing frames and installation of new frames with footings!
I am curious if anyone has experience/knowledge (not always the same thing, btw!) of curing an outdoor pour using steam to get the mix up quickly? I would imagine tents or enclosures can be erected but didn't know if this was practical or not.
Also, beyond type III portland cement and stating a 4,000 psi rating in 3 days, what are other items that generally need specified for High Early Strength Concrete?

But to your main question, the other requirement I placed was no fly ash based on the research I completed. I also requested early breaks at 24, 36, and 48 hours to see if the concrete would make the required strength at 3 days.
Good luck and I would be interested in hearing if your project was a success.

Caneit, we did talk about doing precast footings. The problem I have with that is making sure there is adequate bearing and levelness of the subgrade to ensure they set correctly. I don't know what methods are there to ensure this happens but my experience has not given me a lot of hope that contractors would go the extra mile to see it was taken care of properly.

I have NO idea what this stuff is - but it seems to work and I bet it is expensive. But might solve your problem if you can find out the particulars.

Ron, have you worked with the grout bed idea personally? What are the specs on the grout? I would assume you want something liquid enough to allow the foundation to get worked in level but stiff enough to not let it run everywhere. If that could work, that could allow the precast option to happen as there is room available nearby to stage everything.

Its actually 400 psi in 4 hours...4000 psi in 4 hours would be insane

If it is only the footings, just use 10000 psi concrete and be done with it.
