Annotation: In the paper the history of the SCC emergence and the main directions of its research has been considered. It has been presented the main features of the composition and the structure of SCC as a generalized recipe, fundamental differences between its components by geographic attributes, positive qualities and shortcomings taking into account their impact on the quality of the resulting mixture. The prospective application area of SCC jointly with polyhedral metal pipes as part of the composite bearing structures for the urban conditions has been stipulated. The process of mechanical testing of concrete cube-shaped samples under axial compression, performed in two steps, with the purpose to select the composition for the with the purpose to select the composition for the SCC of low classes (marks) of the SCC, without using of mineral binders and with the required degree of motion of the concrete mixture, is described. As a result, the compositions of SCC with strength class B20…B40, has been found out. The cost of the resulting compositions has been determined, which in comparison with the cost of classic heavy concrete was lower.
Keywords: self-compacting concrete, dosages of components, motion of mixture, dispersed filler, super plasticizer, mechanical tests.
