In a 2019 concrete study, replacing up to 30% of sand with waste tyre rubber increased impact resistance but reduced compressive strength

Utilizing discarded tyres in concrete significantly improves impact resistance. The incorporation of rubber allows structures to flex rather than break under sudden stress. While replacing sand with more rubber may reduce compressive and tensile strengths, this rubberized concrete still serves well in applications requiring impact absorption. This innovative approach not only enhances construction durability but also addresses waste management issues through recycling.
