Recipe for lightweight concrete? - Instructables

It's made by mixing ground styrofoam with concrete. It can be made light enough to float on water. For fine detail, use the finest grade sand you can find, and add a plasticizer (Kongcrete) and fly-ash for workability. You can increase the detail by spraying a face coat with straight concrete, then filling the rest of the volume with EPSCrete.
