Abstract: Assembled structural components, fabricated from cementitious, fibrous, clay, and aggregate materials, have fibers aligned parallel to tensile forces to form a load bearing structure for use in construction. Fiber and cement membrane components hold rigid core parts in the same relationships as membrane components hold organs in animals. These parts force membrane components apart at selected places to tension and protect membrane components from compressive forces. Facing units are interlocked with membrane faces in parallel alignments. A system of ventilating holes and openings prevents damage due to heat.
