"Revolutionizing Concrete Strength: How Coffee Grounds Boost Performance by 30%"

Researchers from RMIT University in Australia have discovered that used coffee grounds can be used as a substitute for sand in concrete production, resulting in a 30% increase in strength. By pyrolyzing the coffee grounds at 350 degrees Celsius, the organic waste can be transformed into a material that forms a stronger chemical bond with other concrete ingredients. This innovation not only reduces greenhouse gas emissions from coffee waste but also helps alleviate the global sand shortage caused by concrete production. The findings offer a promising way to recycle organic waste and reduce landfill contributions.
