Summary draft #1 - Coal ash into concrete
The NaturalBlaze.com article, "Researchers Turn Waste
from Coal Power Plants into Concrete" (2019), reports that researchers
from Drexel University have discovered a sustainable solution to protect the
natural environment and improve the built environment by recycling coal ash.
Tens of millions of tons of coal ash, a less harmful byproduct of coal-fired power
plants, end up in landfills each year. The article also states that by turning
the waste product into a special concrete additive, it will improve the
durability and quality of concrete (as cited in the journal “Cement and
Concrete Composites”). The article also states that proper mixing and curing is required to use concrete without any drawbacks. Hence, the special concrete additive will shorten the time for concrete to harden. Using this method, it will reduce the number of
coal ash in landfills and benefits the concrete industry.
