Australian Studies Explore Recycled Glass and Rubber as Partial Sand Replacements in Concrete
Australian studies show that replacing natural sand in concrete with recycled materials like crushed glass or tyre rubber can enhance certain properties. Up to 30% crushed glass replacement increased compressive strength by 6-9%, while up to 60% glass improved strength and chloride resistance. Incorporating up to 30% crumb rubber from waste tyres significantly boosted impact resistance but reduced compressive strength. These findings suggest sustainable alternatives for construction materials that address waste management and resource scarcity.
