in your part of the country ... maybe it wont.
here in the east/central? the ground moves so much season to season that almost every pad cracks.
like you, i had at least 6-8" of crusher run that had been down for 4 years before we moved in & then we compacted on top of that... PLUS i went with the extra strong mix with fiber & the whole rig a ma row.... it should have worked out to be good for 6,000 psi mix & the slump cone was perfect.
so i dont know if it was crappy concrete coupled with getting a crappy job... or if it was a combination of a crappy job with my luck ran out.
any way it went: ended up with a bad job, bad floor & a very unhappy wife who wanted my floor to be good enough to put tile on.
YOU look like your getting a fine job on YOURS!
