ABSTRACT:
A process and apparatus for making a plurality of building modules each having a foam core encased in a shell of fiber reinforced cement. A bottom layer is cast and fiber reinforced in a casting zone having side rails along a base and division members corresponding to the lengths of the modules being formed. End members are placed on top of the division members and foam cores are placed on the bottom layer between end members leaving free space between the core member, the side rails and the end members. Wet cement is applied to fill the free space surrounding each core member and to form a top layer which covers each core member thereby separately encasing each core member. Fiber reinforcement is applied to the top layer and a plurality of cured modules are removed from the casting zone.
