Concretes without admixtures and of high cement content, (over about 460 kg/m 3) are liable to prove difficult to pump, because of high friction between the concrete and the pipeline.Cement contents below 270 to 320 kg/m 3 depending upon the proportion of the aggregate may also prove difficult to pump because of segregation within the pipe line.
