Describes prefabricated components of lightweight aggregate concrete (LAC) with open structure and with structural or non-structural reinforcement intended to be used in building construction a) for structural elements: - loadbearing wall components (solid, hollow core or multilayer); - retaining wall components (solid) with or without surcharge loading; - roof components solid, hollow core or multilayer); - floor components (solid, hollow core or multilayer); - linear components (beams or piers). b) for non-structural elements: - non-loadbearing wall components (e.g. for partition walls); - cladding components (without fixtures) intended to be used for external facades of buildings; - small box culverts used to form channels for the enclosure of services; - components for noise barriers.
