DESIGN OF CONCRETE PUMPING CIRCUIT

DESIGN OF CONCRETE PUMPING CIRCUIT. Pumping is a technique used for the transport of freshly-mixed concrete, allowing the supply of fresh material in the formwork without the use of any bucket or conveying belt. This article reports on a study on pressure and flow during concrete pumping. The authors used a 150 m-long experimental pumping ...

Design of Concrete Pumping Circuit

Mar 01, 2005  Pumping is a common process to transport fresh concrete. To date, however, there is no rigorous, scientifically based method to design a pumping circuit that is to predict the relationship between pressure and flow rate as a function of circuit dimensions and fresh concrete behavior. Such a method was developed and is presented in this paper.
