What are the technical characteristics of concrete pumps

Assessment and prediction of concrete flow and pumping

Mar 01, 2020 · Concrete flow in a pipeline is a complex material response to the induced pressure accompanied by shear in LL [], friction between solid particles and pipe wall [10,18,19], and significant hydrodynamic interactions among particles within the partially sheared concrete bulk [20,21]; cf. Fig. 2.The extent to which frictional resistance is active depends on the state of saturation of the concrete

concrete, care should be taken to avoid segregation. For example, if dropped too far, the heavy or big aggregate particles can settle and lighter mix com-ponents, such as water, tend to rise. The concrete is conveyed from the mixing truck to its final desti-nation in dump buckets by cableways or cranes or by pumping through pipelines.

Fundamentals Of Pumps

Centrifugal pumps can also be constructed in a manner that results in two distinct volutes, each receiving the liquid that is discharged from a 180. o. region of the impeller at any given time. Pumps of this type are called double volute pumps (they may also be referred to a split volute pumps).

Pumping of Concrete: System, Working and Problems

Pumping of concrete is economical if the quantity of concrete required is more than about 1150 m 3 or uninterrupted supply of concrete is needed over a long period as at the beginning of each period of pump­ing the pipes have to be lubricated by mortar (at the rate of about 0.25 in 3 per 1000 m length of 150 mm diameter pipe) and also at the end of the operation considerable effort is needed

What Makes Concrete Pumpable?| Concrete Construction Magazine

Nov 01, 1991 · In a pump line, concrete moves in the form of a cylinder or slug separated from the pump line wall by a lubricating layer of water, cement, and fine sand. To keep moving through the line, the mix must be dense, cohesive, and have sufficient mortar. When concrete is pumped, if spaces or voids between aggregates are not filled with mortar, or if the mortar is too thin and runny, pump pressures
