Abstract
Concrete products possessing properties far excelling those of conventional autoclaved concrete products are obtained by placing fresh concrete mix in molding frames adapted to withstand elevated temperatures and increased pressure, closing the filled molding frames airtightly, and heating the molding frames and the concrete mix held therein while inhibiting completely the leakage of water from within the molding frames and thereby allowing the concrete mix inside the molding frames to be cured while in a state of being maintained at elevated temperatures under increased pressure.
