    Hydration products. The products of the reaction between cement and water are termed "hydration products." In concrete (or mortar or other cementitious materials) there are typically four main types Calcium silicate hydrate this is the main reaction product and is the main source of concrete strength. It is often abbreviated, using cement chemists notation, to "C-S-H," the dashes indicating 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.
