A World Record in Long Distance Pumping » Equipment

Sep 05, 2017 · The total pumping distance is of 1.36 km on the upstream side and 2.432 km on the downstream side. An important part of the pipeline is the clamp wherein very high pumping pressure takes place. The concrete pump could be operated on both sides, i.e the piston side (for long distances) and the rod side (for short distances).

Aggregates for Concrete - Memphis

Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural
