Just saw a stat that a bad concrete mix can lose over 30% of its strength
Found it in a study from a university lab, and it made me double-check every batch sheet now. Has anyone else run into a supplier giving you a weak mix recently?

Yeah, that "bad concrete mix" line got me too. I used to trust the specs, but after seeing what happened to kim.sarah's crew last year, I check everything now.

That study is interesting but feels a bit off. Danielnelson, I get the worry, but in my experience, a truly bad batch that loses that much strength is super rare if you're using a decent supplier. Most of the time, the real problem is on-site handling, like adding too much water or poor curing. Seen way more issues from rushed finishing in hot weather than from the plant itself.
