J Currelley says a lot of the damage and deaths were caused by poor quality concrete, in part from a weak host rock and in part from lousy concrete making skills. The Georgia Tech guys found that they can double the strength of the concrete by mixing am making it properly which is a Good Start.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>>...Homes built up entirely out of rubble removed ex crushing or with a minimum of same.

As every home needs a roof and a stove, the connection seems obvious: make as much of the stove as possible from crushed rubble.
