Title of the articleTechnology of device and quality control of monolithic steel-fiber concrete slabs using emptiness-formers
Abstract.Problem statement. The purpose of this work is studying the features of the technology of monolithic slabs with emptiness-formers, to identify its disadvantages and suggest ways to eliminate them. Results. At the first stage, the reasons for the low quality of monolithic slabs with emptiness-formers are studied and the ways to eliminate the identified disadvantages are proposed. At the second stage, the main defects and damages arising in construction, repair and operation of these floor slabs are determined. At the third stage, the features of the quality control system, carried out directly at the production of monolithic slabs with the use of emptiness-formers, operation list and control means are proposed. Conclusions. The significance of presented results for the construction industry is to improve the quality of monolithic slabs using emptiness-formers. The use of steel fiber concrete slabs with a unrecoverable emptiness-formers allows to reduce the percentage of reinforcement by 9,82 %, compared to the other studied form of slabs and to reduce the consumption of concrete compared to a solid monolithic slab almost two times.
Keywords.lightweight monolithic slab, an efficient structural shape, unrecoverable emptiness-formers.
