Is Type IL cement really the reason concrete started acting different, or did it just expose the problems we already had?

Type I/II cement may be making a comeback because contractors, producers, and owners want concrete to act like concrete again.

But Concrete Bob Higgins says we need to be careful.

Because before Type IL showed up, the concrete industry still had scaling, dusting, cracking, bad curing, water problems, surface failures, and specs that cared more about 28-day strength than long-term durability.

So if Type I/II comes back, will the problems go away? Or will we lose our favorite excuse?

In this episode, Seth and Bob talk about what really changed in cement, why older concrete behaved differently, why today’s concrete may be more sensitive than the standards admit, and what the industry needs to fix before it repeats the same mistakes.

Type IL may have exposed the problem. But it may not be the whole problem.
