A new technique to predict concrete pumping

Rheological approach


Almost 90 years have passed since concrete pumping was first applied in 1927. Pumping is now a universal method for transferring and placing concrete. However, the pumpability is still evaluated in a qualitative manner on the basis of an engineer’s experience or by a simple experiment, such as a slump test. A technology for the quantitative prediction of targeted flow rate, required pressure, pumpable distance or height, and required flowability of fresh concrete has been recently developed and applied to construction sites. The technology may be very useful in scheduling concrete placement, planning relevant construction processes, and estimating or reducing construction period and expenses. The present article introduces the new technology for concrete pumping prediction.
