    Some research out of Louisiana Tech on Geopolymer Concrete (GPC) which is made using fly ash and is being developed as a substitute for Portland cement. They say GPC has ” greater resistance to corrosion, more fire resistance, greater strength and less shrinkage” although I haven’t seen any numbers.

    They say it’s more expensive, but I don’t know how considering you could probably get fly ash dirt cheap since it’s just a by-product that coal plants need to dump anyway.

    Interesting, though.

    Cement requires a lof of energy to produce. Energy is probably a major part of the cost..

    Highly “User UNfriendly”… As a highly corrosive alkali, it may not be suitable for reiforced structural use…

    It’s not even new technology. It’s been used for over half a century. La.Tech. has a newer formula, but it’s not “new.”
