Roychand et al. show that the leaching of organic compounds from waste coffee grounds hinders the hydration reaction of cement particles, thereby significantly hampering the compressive strength of waste coffee ground-blended concrete; however, pyrolyzing waste coffee grounds at 350 degrees Celsius led to a significant improvement in its material properties, which resulted in a 29.3% enhancement in the compressive strength of the composite concrete blended with coffee biochar.
