Fast, easy tutorial from Lenore of Evil Mad Scientist Labs. I wonder whether you might not use polystyrene beads as an aggregate to reduce weight?

I have quite a bit of experience making lightweight concrete for the national concrete canoe competition. http://content.asce.org/conferences/nccc2009/
