A group of scientists from RMIT University in Australia is working on a method that involves adding coffee grounds to concrete, which could increase the durability of the concrete by up to 30%. After achieving successful results in a lab setting last year, the team has now begun testing this method under real-world conditions. If these tests yield positive results, a major transformation could begin in the concrete industry.
Coffee Grounds Turn into Biochar When Heated at High Temperatures
Researchers convert coffee grounds into biochar by heating them at high temperatures before adding them to concrete. This process prevents the coffee grounds from dissolving over time and enhances the durability of the concrete. Additionally, the team has tried the same method using sawdust and achieved similar results.
This new technique has the potential to reduce carbon emissions and lower concrete costs. However, more testing and time are needed to see if these findings can be applied on an industrial scale.
