Analysing the Suitability of C16/20-X0v(H)-24-F3 Concrete for Pumping

Abstract

The current paper introduces a case study dealing with the problem of pumpability of the ready-mix concrete of grade of C16/20-X0v (H)-24-F3 []. During solving a practical industrial problem we have worked out a modified composition of the related concrete material in order to improve the pumpability. After describing some possible theoretical and practical methods the authors give suggestion for a practical solution. The characteristic feature of the method consists in modifying the recipe of the given grade of concrete without altering the additive structure, and to assure the pulp saturation. The paper reports the results of standardised physical and mechanical tests, executed on the novel concrete material. Based on these results it has been proved, that besides solving the original practical problem of pumpability, the new concrete material possesses better application and technological performance, and is more economical to produce.
