A Review on the Pumping Behavior of Modern Concrete

Pumping is the most common technique used to transport fresh concrete in construction sites. The large-scale use of concrete all over the world makes the pumping increasingly important. A wide variety of additives and admixtures are incorporated into modern concrete in order for sustainable development.

18/12/2017 · The most common problem of pumping concrete is blockage. If the pump is mechanically sound, the failure of concrete to emerge at the end of the pipe line is called blockage. The increase in the pressure shown by the pressure gauge of the pump is the indication of the blockage of the pipe line.

Change in fresh properties of high-strength concrete due …

Concrete pumping plays an important role in modern construction and is frequently used to accelerate and facilitate concrete placement. Pumping can lower the costs and shorten the construction duration by offering a speedy and continuous mode of concrete placement and allowing the concrete to be delivered in difficult-to-access locations [1] .

Pumping is the most efficient transportation and placing method for concrete. Despite the immense progress in the field of concrete technology in the last years, so far there are still neither official regulations nor verified theoretical foundations to be used for the assessment and accurate prediction pumping behaviour of ordinary and high performance concretes.

1/5/2018 · The box must contain at least one transparent side; the granular material is placed on the base of the box, and then the box is tilted gradually at a rate of 18°/min. The angle of repose is then measured as the tilting angle at which the material begins to slide [ 7, 35 ], as shown Fig. 2.
