Abstract
A method of producing gas concrete. A castable mass is prepared by mixing water, a lime component including lime having a t.sub.60 value of less than ten minutes, and a sand component. A calcium sulphate-containing component is subsequently admixed and a rising agent, such as aluminum powder, is subsequently admixed. The mass thus prepared is cast into molds and fabricated into gas concrete by the conventional steps of permitting the mass to rise and harden, cutting the hardened material to size, and hydrothermally curing. The process makes possible the use of readily available inexpensive lime material without the disadvantages normally resulting from use thereof.
