       | This is brilliant. It's like asphalt, which is just concrete
       | (cement, sand and lime) with some of the cement replaced with
       | oil/tar. This is that same idea but using plastic not oil/tar.
       | 
       | Truly brilliant. It's a new type of composite building material.

       | Wood, stone, pretty much everything is stronger than concrete. We
       | use concrete because it's strong _enough_ and cheap (and doesn 't
       | rot like wood, but a lot of things don't rot so that's not too
       | novel).

         | Two points:
         | 
         | 1. The article says its "cheap" for what that's worth.
         | 
         | 2. This IS concrete. It's a mixture of sand as aggregate and
         | plastic as a cement AKA binding agent.

         | Unless you get an alkali silica reaction (aka concrete cancer).

       | When the concrete weathers, will the plastic in the bricks turn
       | into micro-plastic?

       | even more places within the foodchain.
       | 
       | Wonder if it burns nicely too, plastic after all is "frozen
       | gasoline" - here mixed with sand.
