Scientists use processed coffee grounds to make stronger concrete
2023年8月28日小于 1 分钟
In an idea that fittingly
arose over a cup of coffee, researchers have devised a technique to recycle used coffee grounds to make stronger concrete
. Engineers at RMIT University say they have developed a way to make concrete nearly 30% stronger by incorporating
processed coffee grounds into the material. The researchers have converted
waste coffee grounds into biochar
, a lightweight
residue
similar to charcoal
, and used that biochar to replace a portion of the sand
required to make concrete.
