Stronger Concete with Irradiated Plastic

Oct-27-17 A new technology from MIT strengthens concrete with irradiated plastic bottles.

Previously, adding plastic to concrete has made the concrete weaker. To overcome this obstacle, the student team exposed the plastic to gamma radiation, which made the material stronger. The plastic was ground into a powder mixed with cement, resulting in concrete up to 20 percent stronger than standard versions. The irradiated plastic also holds no trace of radiation, and so is safe to use.
