In-site transportation of concrete mix: new typology of methods, potential and fields of modern mechanization means’ rational application

The main structural material in construction industry is concrete. article discusses the features of modern methods and means in-site transportation mixture that subsequently forms it and, particular, its supply to concreting blocks monolithic structures. requirements Russian norms for this process implementation, as well world practice using machines, equipment devices intended this, are analyzed. A new typology concrete proposed, based on differences between them type resource intensity moving action. Generalized, systematized brought applied form information about productivity parameters mechanization corresponding working zones, technological properties influence possibility their use. data obtained made possible clarify rational use areas types such technology reveal contradictions associated with this. In general, research results presented facilitate identification shortcomings promising directions improving considered competing technical means, justification choice them.
