The present invention relates to a novel cement composition. This cement may be combined with a number of different products, including residual materials such as polystyrene, glass, cork, fiberglass, cellulose fibers, wood fibers and wood shavings, as well as with minerals or compositions such as zonolite or vermiculite. The resultant concrete exhibits physical and chemical characteristics that make it suitable for use in construction projects, including resistance to freeze-thaw cycles.
