Cover Story: A new concept of concrete modular construction, in which each module is made up of six-bilayer-stiffened panels, is proposed here. The first layer, an EPS insulation material, serves as permanent formwork, in which a self-compacting concrete, with 80 kg/m3 of steel fibers and 0.3 kg/m3 of PP fibers, was poured and casted. After 7 days, the four stiffened walls, 5 cm thick, and the two stiffened slabs, 7 cm thick, are factory-assembled to form a module; meanwhile, foundations and technical connections (water, electricity) are prepared. The modules are then transported by truck 60 days after their production, and a crane positions them according to the plan. The heaviest module weighs 36 tonnes. Bolted metal plates ensure foundation-to-module as well as lower-to-upper-module connections, while mortar joints ensure stability and tightness. View this paper
