Concrete using recycled tire rubber hits the road to a circular economy
Engineers from RMIT University have managed to replace 100% of conventional aggregates in concrete – such as gravel and crushed rock – with rubber from discarded tires that meets building codes, promising a boost for the circular economy.
Researchers say the new greener and lighter concrete also promises to reduce manufacturing and transportation costs significantly.
Small amounts of rubber particles from tires are already used to replace these concrete aggregates, but efforts to replace all of the aggregates with rubber have produced weak concretes that failed to meet the required standards – until now.
