Experimental studies of influence of concreting technology on strength characteristics of fiber concrete

The accumulated base of research results on steel fiber concrete properties confirms a positive effect of the steel fiber on physical and mechanical properties of concrete and reinforced concrete products and structures. Therewith, one of the constraints for the use of steel fiber concrete in design and construction of buildings and structures is the dependency of fiber content in the unit of steel fiber concrete mixture volume and fiber strength performance on the mixture compaction technology. According to the purpose of the work, experimental researches were carried out on the effect a steel fiber concrete mixture compaction technology has on fiber distribution and strength variation of steel fiber concrete samples under compression along the section height of a solid slab foundation. The obtained results allow for evaluating the possibility to use standard methods of steel fiber concrete mixture compaction during concrete pouring of structural elements
