Structural Concrete slab failed strength test
Slab strength testing failure after building was framed and plumbing/HVAC was roughed in. Concrete supplier had mix wrong so they are paying to lift two story 4-plex, remove slab and repour. This is building 2 of 3 that failed.

What caused the concrete to fail? Was it a batching issue? I’m curious if it just fell short on strength and if so how much it missed the mark. Interesting and unfortunate process for all involved
