Abstract
An insulated concrete form wall building system includes a pair of spaced apart elongated expanded polystyrene sidewalls, each having opposed inner surfaces that are formed with longitudinally spaced apart vertically oriented ribs that terminate in substantially flat surfaces to abut against one another to serve as a concrete wall form. The ribs define channels for receiving concrete poured therein to form a composite polystyrene and concrete wall structure.
