Engineers in Australia make concrete out of rocks, rubber, and tires.
The traditional process of creating concrete, which uses crushed rock and gravel, has been successfully replaced by a team of researchers from the Royal Melbourne Institute of Technology (RMIT) using rubber from used tires that comply with construction requirements.
The university's press announcement claims that new, lighter, greener concrete also promises to drastically lower manufacturing and transportation costs. These concrete aggregates have previously been partially replaced with rubber fragments from tires. However, the earlier method of removing all of the concrete and replacing it with aggregates had failed.
The production of tires was demonstrated in the study that was printed in the journal Resources, Conservation & Recycling.
