A process of molding a building panel which includes the steps of combining about 25 pounds of Portland Cement Type I, about 15 pounds of water at around 21 DEG Centigrade, added about 1 ounce of aluminum, calcium, magnesium, and silica, respectively, and about 12 ounces of synthetic fibers with about 0.1 ounce of ferro chloride in 40% solution by volume, and pouring the mixture into the lower portion of a mold to about 1/2 its depth and waiting for approximately 4 hours for the mixture to increase by about 100% of its original volume to fill the mold and thereafter stripping the mold from the form and placing it in a heated environment for curing for a period of approximately 24 hours and thereafter removing the panel from the heated environment. The panels according to the process are preferably provided with a peripheral groove in the side and upper surfaces so that when placed in generally co-planar relation, a cavity is defined between adjacent panels in which there is a steel reinforcing rod embedded in a pour of concrete to form a wall.
