Pumpable Concrete Mix | Pump Mix Concrete | Eastern
Pumpable concrete mixes simplify concrete application by having it applied through a lubricated pumping system, and exits (with minimal friction) through a focussed plug, top generate pressure. The ideal mix of concrete for pumping needs to be mixed to facilitate reliable pumping without undermining the integrity of the concrete itself.

THE MIX DESIGN AND PROPERTIES OF PUMPED CONCRETE
Jan 01, 1976 · A pumpable concrete mix must be able to maintain its consistency in pump and pipeline. Where rapid changes occur in cross-section of the pump or pipe, 2 or at high rates of placing pump pressures as high as 5MPa (5 MN/m ) may be needed, with corresponding severe pressure gradients in the concrete.

CONCRETE 101
Slump is a measure of concrete consistency or fluidity. Consistency is the ability of freshly mixed concrete to flow. For given proportions of cement and aggregates (without admixtures), the higher the slump, the wetter the mix. Four-inch (4") slump is very common with normal weight concrete and is a good average slump for pumping.

Principle of mix design for pumpable concrete
Sep 23, 2020 · A pumpable concrete, like conventional concrete mixes, requires good quality control, i.e. properly graded uniform aggregates, materials uniformly and consistently batched and mixed thoroughly. Depending on the equipment, pumping rates may vary from 8 to 130 m 3 of concrete per hour. Effective pumping range varies from 90 to 300 meters horizontally, or 30 to 100 meters vertically.
