Recycled carbon fiber improves concrete drainage capacity during the flood season

Research team from University. Washington State, USA recently found a solution to high-tech waste when using used carbon fiber to improve concrete drainage.

The carbon fiber manufacturing industry is gradually growing but also has implications for growing demand for recycling if it does not want to pollute the environment.

Used carbon fiber applications to improve the drainage of concrete.

But according to a study by the University. Washington, used carbon fiber in addition to recycling can also be crushed, mixed into concrete to improve the water's permeability.

Water-repellent concrete is a type of concrete with high porosity and rapid drainage to the surface of the soil when it rains. In many places, water-repellent concrete has been applied a lot to prevent flooding and pollution of the environment and landscape after flooding.

Meanwhile, traditional concrete does not absorb water and water when flowing on the surface will often roll along a long path before accumulating in low-lying areas.

But due to the large porosity, the bearing capacity of absorbent concrete is also less than that of traditional concrete. Therefore, this type of concrete is seldom used on large roads, traffic flows through it.

This type of concrete is seldom used on large roads, traffic flow is large.

Despite this, the top two scientists Karl England and Somayeh Nassiri belong to the university. Washington believes, new research on the applicability of carbon-fiber composite materials will open the prospect of developing a durable water-proof concrete on par with traditional concrete.

The team has grinded carbon fiber composite materials , then mixed with a water-proof concrete mixture to test durability. The results are quite surprising when the small carbon fiber is capable of homogeneous dispersion, reinforcing and strengthening the water-proof concrete block.

According to Nassiri, the co-author studied: 'In terms of bending ability, new concrete has the same bending level as traditional concrete while the drainage capacity is still extremely fast'.

Besides, because carbon fiber is put into concrete, there is a composite form, so there is no need to undergo heat treatment or adding chemicals.

Composite carbon fiber has become an almost popular material in the industry. Thanks to its ultra-light, durable, toughness, the material is used to produce from airplane wings to wind turbines or cars.

Although the market for carbon fiber composite materials is growing hot, 10% per year, the industry still cannot find a solution to the problem of recycling waste, including 30% of waste materials in the production process. material.

The team has demonstrated the effectiveness of the technology in the laboratory scale and is considering large-scale testing in the near future.

The above research by American scientists was published in the famous Materials in Civil Engineering magazine in early March.
