Annotation: The theoretical basis of the stream concreting technology with using of elastic throwing devices is the new naturally scientific essence of mechanical, physical and chemical processes which are the basis of the tough fine-grained concrete mixture transformation in the especially dense high durable concrete of the thin-walled constructions. With researches getting of high-dense fine-grained concretes of the thin-walled constructions in the conditions of construction site, it has been established that most effective solution is the methods of the stream concreting technology, while realization of which the concrete mixture, being regenerated to the discrete particles flow, is densed under act of very intensive inertial forces action. Recently technical means technology of concreting were used mainly pneumatic apparatus: cement-cannon and injector machines. But in connection with considerable power capacity, complication and metal capacity of technological equipment, the pneumatic methods of stream technology as before are used restrictedly. The situation changed in the interest of stream concreting technology, when for getting of dense concrete for building constructions the method of rotary condensation, while which concrete packing with condensation was carried out by means rotors which were revolving with the certain speed.
Keywords: stream concreting technology, elastic devices, thin-walled constructions.
