What #11 Grade 60 Rebar looks like when stretched to breaking in slow motion

Happy Friday, everyone. As a treat, here is a cool video from The Slo Mo Guys taken at a testing laboratory at Purdue University.

Reinforced concrete is truly an amazing product that is critical to the structural design and integrity of most modern buildings. The utility of the material comes from its ability to resist both compressive force as well as stretching. Concrete on its own has great compressive strength, but relatively little tensile strength without steel reinforcing.

That’s fairly common knowledge among most people in the building industry, but how many people can say that they’ve seen what rebar looks like when stretched to breaking?
