Simple tools cut, rasp, or drill the elements. Workability is easier than wood. Windows and doors can be simply cut out. Use the elements in either direction in the way they will fit the building plan best. The cavities, which form the structural part once concrete has been grouted, always line up.
Concrete is grouted after a complete story has been set up.
Arches are pre-cut and concrete blocked off for grouting. The cut out elements will be taken out later and can be used somewhere else. Rounded edges, pillars, millwork can be made by simply cutting and rasping. Roof and walls are poured at the same time to form a monolithic structure. All rights reserved.
