| Truly brilliant. It's a new type of composite building material.

| 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.

| Wonder if it burns nicely too, plastic after all is "frozen
