This seems amazing to me - take trash plastic, grind it up, irradiate it with a food-grade tool, then mix it with Portland cement 98.5/1.5 and it makes the resulting concrete 15% stronger - and the resulting concrete can still be reinforced by normal means. You're taking trash, applying a tool that is already in widespread use, and getting a better end-product out of it? Apparently the world consumes 10 billion tons of cement per year [0]; that means that we can dispose of 150 million tons of plastic bottles using this technique. There's gotta be a catch - this seems amazingly good. [0]: http://concretehelper.com/concrete-facts/ http://concretehelper.com/concrete-facts/
