A significant amount of concrete produced in Australia is transported and placed by pump. This recommended practice was prepared because of the importance of the pumping of concrete in Australia to-day. The successful pumping of concrete is dependent on a number of factors including using the correct pumping and line arrangement, having a suitable concrete mix and setting up a satisfactory communication system between the builder, the concrete placer, the pumping contractor and the concrete supplier. This recommended practice discusses these factors and includes a summarised history of the introduction of the smaller line pumping into Australia in the 1960's.
