Using rocks larger than this size in the material could

Reported by ACI Committee 304 ACI 304.2R-17

Pumping concrete through metal pipelines by piston pumps was introduced to the United States in Milwaukee, WI, in 1933 (Ball 1933). This concrete pump used mechan-ical linkages to operate, and usually pumped through pipe-lines 6 in. (150 mm) or larger in diameter. Many new developments have since been made in the concrete pumping field.

THE MIX DESIGN AND PROPERTIES OF PUMPED CONCRETE

Mix Design for Pumped Concrete with PPC, OPC, OPC+Flyash A concrete of less than 50 mm slump is impractical for pumping, and slump above 125 mm should be avoided. In mixtures with high slump, the aggregate will segregate from the mortar and paste and may cause blocking in the pump lines.
