The use of concrete

Now instead of fixing pre-cast concrete panels to the frame is applied layer by layer throwing him on the concrete with subsequent retention. In some cases, the concrete had been sprayed on the lightweight precast frame, which plays a role of reinforcement. In another system used shotcrete concrete contains tiny fibres that give it even more strength. Concrete has become one of the most important materials for the manufacture of prefabricated structures such as beams and columns, floor slabs and roofs, staircases, cladding wall panels and load-bearing structure of the walls. In some structural systems, such wall elements support the weight of the entire building and there is no need in the bearing frame of columns and beams. Concrete panel exterior walls come from the factory ready with a decorative veneer and is often inserted by Windows.
