According to foreign media New Atlas, although the production of carbon fiber products may grow steadily, recycled materials are still challenging. Now thanks to an ongoing study by Washington State University, carbon fiber scrap may soon be used for new and improved permeable concrete. First of all, what is permeable concrete? It is a kind of porous concrete, and the rainwater runoff can pass directly into the underlying soil. Not only does it help prevent flooding, it also reduces water pollution - using traditional impervious concrete, it runs along the length of the road, accumulates more and more pollutants along the way, and then enters the local waterways. Unfortunately, because of its good water permeability, permeable concrete is not as durable as ordinary concrete. This is why researchers decided to add carbon fiber waste. A team led by Karl Englund and Somayeh Nassiri used a cheap mechanical grinding technique to grind carbon fiber scrap from Boeing. When the milled carbon fiber is added to the team's existing permeable concrete mix, the durability and strength of the resulting material are greatly enhanced. Nassiri said: “In terms of bending strength, we have achieved very good results - it is as high as conventional concrete, and its drainage speed is very fast.†In addition, since carbon fiber remains in its cured composite form, it does not require Heat or toxic chemicals to handle it. Scientists have demonstrated the effectiveness of this technology for laboratory samples and now wish to conduct large-scale testing. The paper on this research was recently published in the Journal of Civil Engineering Materials.
