Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

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.

Most vertical mixes are composed of a blend of cement, graded lightweight aggregates, polymers and admixtures. Some are also fiber-reinforced. They are mixed with a paddle or mortar mixer and then applied with a hand trowel, similar to plaster, or even with a shotcrete gun, depending on the size of the area to be resurfaced.
