摘要: In this paper, recent developments in evaluating pumping behavior of flowable and self-consolidating concrete (SCC) are discussed. First, a brief overview the underlying physics is given to introduce concepts friction, flow, hydrodynamic hydrostatic pressure present concept lubrication layer. Various methods assess layer properties then discussed, including tribology different visualization techniques for velocity profile. Using on one hand, or by combining rheological its constituent mortar knowing thickness other it shown that losses during can be successfully predicted. An also provided discuss influence flow rate, pipe diameter critical SCC influencing pumping.
