Process of continuous manufacture of light-weight foamed concrete

摘要

Light-weight foamed concrete articles are advantageously manufactured in a continuous manner from a rapid setting hydraulic cement composition. The cement composition in the form of a dry powder and an aqueous foamed liquid containing a foaming agent and a setting retarder are separately and continuously introduced into a continuously stirred vessel where they are mixed into an aqueous foamed cement slurry within a short period of time. The foamed cement slurry is cast into the desired shape and, if desired, cured.
