The process of mixing concrete becomes more difficult after water is added. This mixture is then spread out to a thickness of 200 mm and sprinkled with water. The mixture is continually turned over until a consistent colour is produced. Because hand mixing cannot be comprehensive, it is preferable to add some additional cement (10%) …

Concrete being pumped through a line experiences friction with the internal wall of the pipeline. The longer the line, the more friction encountered. For longer pumping distances, the use of smooth-walled steel pipe can lower the resistance. The length of hose used at the end of the pipeline adds to the overall line length as well.
