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 types and improvements. Pervious concrete.
First of all, what is pervious concrete? It is a kind of porous concrete. Rainwater runoff can pass through directly to the underlying soil. It not only helps prevent flooding, but also reduces water pollution - using traditional impervious concrete, along the road Driving along the length, accumulating more and more pollutants along the way, and then entering 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 ground carbon fiber was added to the team's existing permeable concrete mix, the resulting material was durable. Sex and intensity are greatly improved.
Nassiri said: 'We have achieved very good results in terms of flexural strength - it is as high as conventional concrete, and its drainage rate is very fast. 'Also, since carbon fiber remains in its cured composite form, there is no need for 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.
