Iranian Researcher Applies Carbon Fiber Waste to Improve Water-Draining Concrete

An Iranian researcher Somayeh Nassiri in cooperation with Karl Englund at Washington State University have used an inexpensive mechanical milling technique to grind up scrap carbon fiber provided by Boeing.

Led by Karl Englund and Somayeh Nassiri, a Washington State research team used an inexpensive mechanical milling technique to grind up scrap carbon fiber provided by Boeing. When that ground carbon fiber was added to the team's existing pervious concrete mix, the durability and strength of the resulting material was greatly increased, New Atlas reports.

"In terms of bending strength, we got really good results — as high as traditional concrete, and it still drains really quickly," says Nassiri.

Additionally, because the carbon fiber is left in its cured composite form, no heat or toxic chemicals are required in order to process it.

The scientists have demonstrated the effectiveness of the technology on laboratory samples, and now hope to conduct large-scale tests. A paper on the research was recently published in the Journal of Materials in Civil Engineering.
