THE TRANSPORT OF FRESH CONCRETE THROUGH PIPES - PREREQUISITES FOR THE PERFECT PUMPING OF CONCRETE THROUGH PIPES HAVING SMALL DIAMETERS

DIE FOERDERUNG DES FRISCHBETONS DURCH ROHRE-VORAUSSETZUNGEN FUER DAS STOERUNGSFREIE PUMPEN VON BETON DURCH ROHRE MIT KLEINEN DURCHMESSERN

This book presents the results of numerous individual studies carried out at the institute for construction operations and construction machinery, Technical University of Berlin, and on a series of construction sites in Berlin and in the Federal Republic of Germany. An evaluation of the tests shows that the pumping of concrete in the rheological sense is a "plug flow" process. A disturbance-free operation can only be expected if the concrete is saturated with cement paste. The work examines all the factors which influence the pumping of concrete, explains the theoretical relations and illustrates the results in tables. The book is intended as an aid to the engineer to enable him to judge whether a concrete having a certain granular structure and a defined binder and consistency can be transported through small-diameter pipes. /TRRL/
