Envelope #30: “I feel like I should know this…” Concrete Refresher

Happy Thursday! Hope you are enjoying the summer (August is just about to be over – can you believe it!?). This is Back of the Envelope – the newsletter where I share things I learned (or relearned) recently, in 5 minutes or less.

Today, I am going to talk about something related to concrete reinforcing that you either:

1. Already know it pretty well

2. Kind of know it but never really looked into it.

3. Used to know it but forgot

What am I talking about?

I am talking about “development length” vs. “Class A splice” vs. “Class B splice”.

It’s one of those things that you say to yourself, “I feel like I should know this, and I kind of do, but not really…”

So let me lay it all out for you.
