Improving Concrete with Recycled Tires
University of British Columbia have determined that the addition of rubber fibers can reduce the formation of cracks by up to 90% when introduced into concrete mixtures. The source of these fibers comes from recycled tires. Therefore,in addition to stronger concrete, this can mean the diversion of tires from landfills.
Currently, the research group supervised by Nemy Banthia is monitoring the real world application of their mix in the front steps of UBC's McMillan Hall. This surface's performance is being monitored for strain using embedded sensors as well as cracking and other factors. So far, the results of rubber fibre reinforced concrete stairs are confirming those found in the lab.
