"You can't do that!"
These words are challenge every building product manufacturer to rethink their attitudes about the limitations of their products. A threaded bolt and nut made from concrete is a good illustration of this principle.
"Everybody knows you need metal to make a high strength bolt!"
Everybody, apparently, is wrong.
In a recent "Concrete Canoe" competition in which engineering students design and construct boats from concrete, one team even build impellers, gears, drive shafts, and ball bearings from concrete. The components were joined with bolts and nuts made of concrete.
Imagination, is a fundamental principle of technology. I think.
