Floor Slabs Which are Frightening From Underneath, But Following Minor Repair Repeatedly Durable

Abstract

The paper is intended to deal with a certain failure of a floor slab type, which was favored in the beginning of the 20th century in Hungary. The main features are: between skeleton ceramic filling elements in situ reinforced concrete beams are prepared during the construction of the relatively narrowly spaced RC beamed slabs. In the studied cases mainly due to the pure workmanship of concrete construction, and/or due to some other influencing factors the bottom surface of the ceilings of such construction systems delaminated. The first underneath sight of such failures are usually frightening, and if an inexperienced person views the result, the statement of the slab to be life dangerous, and it should be reconstructed may be made. At the same time the slab may be saved, and the repair is much more cost eective than demolishing and reconstructing the structure.
