Cement is a binding material made of a mixture of calcareous, siliceous, and argillaceous substances. There are two main processes for manufacturing cement - the dry process and wet process. In the dry process, raw materials are ground without water, while in the wet process water is added during grinding.

5.2 Process of cement manufacture. In the dry process, fuel consumption is lower as compared to the wet process.The dry process is, therefore, preferable if the raw material components are not too wet or sticky. As a fundamental rule, the dry process is to be recommended for reasons of heat economy, 1 particularly in cases where the raw materials contain less than 15%–18% water.

Rubberized mixtures can be produced by wet and dry processes. The wet process is widely used. The dry process involves adding rubber particles into the mixture directly and can consume more crumb rubber than the wet process [95]. The main differences between the wet and the dry process are shown in Table 13.3.4.
