Single-Stage Pumping of Concrete up to 2.432 km (1.51

Oct 13, 2014 · Abstract. This paper reports a systematic study conducted during application of pumping concrete for distances up to 2.432 km at an actual construction site. Admixture design for maintaining flowable concretes through 12 h, while setting within 20 h and developing stripping strength in 30 h was critical. Full-scale field trials for checking field behavior of concrete, pump, their interactions and manpower training are synergistic; weather plays a …
