Abstract

To cast foam concrete bodies, the concrete is poured into a mold with a lower height than the length and width. The poured mass is initially hardened into a foam concrete cube (1). The cube is tipped by 90 degrees from its horizontal lie, to rest on its lower narrow side, to be cut into cubes (1.1-1.5), and the body is tilted again by 90 degrees into the horizontal, and the cut cubes are separated at intervals of 1 mm to 5 cm. After a time span of 5 secs. to 10 mins., they are pushed together, and the body is returned to the vertical position for final hardening.
