Tire Fibers Reduce Concrete Explosions

Feb-20-19 Adding old tires to concrete could help the material channel heat to resist explosion.

Under intense heat, the surface layers of concrete will spall—break off explosively and damage the structure. To help prevent this, the team from the University of Sheffield determined that the fibers embedded in tires as reinforcement can be used to create tiny channels in the concrete that allow the moisture to escape. This method has been used before, but the channels were made using new polypropylene, which is expensive and resource-heavy. In contrast, the Sheffield technique relies on recycled materials that do an equivalent job.
