My concrete is 6.5" to 7.5" thick, fiber reinforced over welded wire on 3" upper slab bolsters. The 7 day test showed 3860 psi and the 28 day test showed 4640 psi.
I did not left them us any curing compounds or sealers.
Final ph needs to be between 8-10.
Thanks again for advice.
I would be using it for one of the applications you mentioned. "In enclosed areas we use H3PO4 for preparation of concrete for the application of Epoxy floor coverings."
I intend to use epoxy floor finish in my personal garage. I had the concrete power trowelled so it's rather smooth in a lot...
