- The appropriate response, Bear, is that they need testing, not outright
- "it won't work". There are, of course, standard ASTM (sorry, I forget the
- new name, NIST?) standards & tests for new materials.
-
- As an example, I worked as a lab tech in the late-60's/early 70's, at a
- research lab. We did work with fly ash from the city incinerator. According
- to the ASTM tests, our cement made with it was stronger than Portland
- cement. Aggregate made with it met or exceeded all standards for general
- use, for things like roads, buildings, etc. My boss tried to interest the
- US gov't in putting up a building at a World's Fair, built completely from
- recycled materials like this. Dear old Tricky Dick & the Republicans (catchy
- name for a group, no?) didn't like the idea. The big trick is overcoming the
- "But we've never *done* it that way!!!" response.
