The greener and lighter concrete replace 100% of conventional aggregates used in concrete, such as gravel and crushed rock, with rubber from old car tyres. The new sustainable concrete adheres to building codes and will potentially reduce manufacturing and transportation costs considerably, boosting the circular economy<\/a>.<\/p>\n Although small amounts of rubber particles from car tyres are currently used to replace some concrete aggregates, efforts to fully replace the aggregates with rubber have resulted in weak concretes that do not meet quality standards.<\/p>\n However, the RMIT team\u2019s sustainable concrete completely replaces the aggregates with recycled rubber and has demonstrated excellent performance.<\/p>\n Mohammad Momeen Ul Islam, the lead author of the study from RMIT University\u2019s School of Engineering, commented: \u201cThe findings debunked a popular theory on what could be achieved with recycled rubber particles in concrete.<\/p>\n \u201cWe have demonstrated with our precise casting method that this decades-old perceived limitation on using large amounts of coarse rubber particles in concrete can now be overcome.<\/p>\n \u201cThe technique involves using newly designed casting moulds to compress the coarse rubber aggregate in fresh concrete that enhances the building material\u2019s performance.\u201d<\/p>\n
