Abstract

Currently, manufacture of steel fibre reinforced concrete (SFRC) takes place in concrete mixer truck for floors mostly of industrial halls. This technology is suitable for low dosages of fibres (about 20kg/m3), which is determined by uncrossable price of deposited concrete (400 – 600 crowns/m2 for the floor in thickness from 150 to 200 mm). Totally realistic premise in future is, that SFRC will be used for load-bearing SFRC structures of aboveground objects. In this case, production of SFRC must take place in concrete plants at higher weight doses than 40 kg/m3 of fibres, to achieve the characteristics of SFRC, which bring effects to SFRC structures. In the paper, there are presented two examples of the production of SFRC in concrete plants. There is specified manufacturing process of production of SFRC in mixers with forced circulation, which is necessary to comply, in order to achieve a homogenous fresh fibre concrete and to minimize wear of machinery.
