$100 Award for a Product Name

looking for a name for a specialty lightweight concrete mixture with these features: LIGHT WEIGHT. STRONG. HIGH IN RECYCLED CONTENT. Product is made "light" and "green" by replacing appx 1/3 of the sand and gravel contained in a typical sack of dry mixed concrete with ground up and specially coated particles of scrap Styrofoam particles diverted from urban landfills. (possible theme: local waste for local benefit) Good luck! Thank you. (Not hot on "ECO" type names - too cliche.)
