| Jan 21, 2013 at 16:55 | comment | added | Ken | My (naive) thinking was that the package would form a steel reinforced concrete beam. | |
| Jan 21, 2013 at 16:27 | comment | added | Michael Karas♦ | I am also fully uncertain about the idea of filling the tube with concrete. It will do next to nothing to make the tube sag less under load. | |
| Jan 21, 2013 at 15:53 | comment | added | Chris Cudmore | I'm not too sure about concrete. It's pretty crappy stuff in tensile loading or bending (which is half tensile). | |
| Jan 21, 2013 at 14:54 | comment | added | Ken | good idea, I'll do that | |
