  • Method of forming a cementitious panel
    Patent number: 6572811
    Abstract: A method is provided for rapidly forming a cementitious panel. A cementitious mixture is introduced into a mold configured to provide the desired surface appearance and profile of the cementitious panel. The cementitious mixture is then subject to an accelerated curing process by applying microwave energy to the cementitious mixture for a predetermined time period. After a relatively short resting or cooling period, the resulting cementitious panel is ready to be removed from the mold.
