Multi-layer lightweight part-concrete building panel - with outer layers of tensile-stress-absorbing material fresh bonded in successive stages

摘要

The panel, for roofs, ceilings or other building elements, comprises a core layer of light concrete with a piled porous configuration, such as expanded clay concrete, pumice-concrete, etc. with two outside closed layers, with all the materials fully mechanically built in, and with the whole thickness of the slab being statically effective. The outer sealed layers are pref. or mortar cement with embedded corrosion-resistant fibres or similar material, accommodating the tensile stresses occurring in corresponding strength, and bonded to the core layer as one fresh material on another in successive working stages. The fibre reinforcement may run lengthways, or be embedded in two or three dimensions. The outer layers may be of plaster or plastic mortar or similarly effective agglomerating compounds, with a corresponding bonding material in the light concrete.
