PHOENIX (3TV/CBS 5) – Construction can be a real headache, but closures lasting weeks or even months could soon be a thing of the past. An Arizona State University professor is researching an alternative way to mix concrete, which can save builders time and money with a result that he claims is just as strong.
“Our goal is to rethink this 100-year-old technology of only using steel rebars,” said Barzin Mobasher, an ASU Civil engineering professor. Professor Mobasher took Arizona’s Family to their concrete lab on campus, where he’s been looking at ways to remove steel rebar from the concrete equation. “At some point, you reach a point where we just can’t do that anymore, and I’ve dedicated my career to this area to show that it’s possible.”
The regular way to make concrete uses steel rebars, and lots of them are put into frames to reinforce it—this new way of mixing in little things instead, called steel fibers, to achieve a similar product.
In this lab, the concrete is put to the test. They can simulate everything from cars driving on it to earthquakes. They even test other fiber mixtures. An ASU science and technology building was recently built using this concrete. Mobasher said crews will save money and time by eliminating steel rebar from projects.
