RE: "Ductal"

I recently got a newsletter from HPC (http://hpc.fhwa.dot.gov) that had a short blurb about Reactive Powder Concrete (aka Ductal).  In the article there was an email address of the guy who provided the information.  I don't want to publish someone else's email, so if you want to contact him, how about request a copy of the newsletter from the website above.  The newsletter is called "HPC Bridge Views" and it is Issue no. 16 (July/Aug 2001).  Basically this type of concrete is very stong (25,000-33,000 psi) in compression and quite impressive for flexure also (4000 to 7000 psi).  It has been used so far in a few pedestrian bridges.
