Abstract: The invention herein is drawn to a plurality of structural products comprising segregated slabs, a process of making such structural products, and apparatus for performing such process of making such products and structures incorporating such products.The product comprises a plurality of slabs connected to each other only by an array of steel bar members extending therebetween and firmly attached thereto, whereby the slabs are movable relative to each other in directions transverse to the length of said bar members to the limit of flexibility of said steel bar members, so that many undesirable yet usually developed stresses and strains and failures developed in conventional reinforced concrete structures are obviated, and a light, strong, low-cost, thermal insulating structure is provided.
