MIT students fortify concrete by adding recycled plastic
Oct 25, 2017 · MIT students have developed a form of concrete using recycled plastic water bottles. The new material is 20 percent stronger than traditional concrete and could help cut the cement industry’s carbon emissions.
Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
Scientists Have Reinforced Concrete With Plastic Waste
The concrete was reinforced using recycled polypropylene plastic instead, and strength and durability tests show that the end result could be used to build footpaths and precast elements such as drainage pits and concrete sleepers. Tuladhar is now working with local concrete producers to find out how to apply the findings more broadly.
