Re: Weight reduction to reduce fuel need. - weight reduction over greater ISP

Concrete had a poor strength to weight ratio.  Concrete is basicly man made sandstone.  Yets, it's stonger then most, but that is basicly what it is.  I believe the geological term for it is Quartenary (sp) Conglomerate.
