Portland cement - ScienceDirect

Portland cement is a complex product made from very simple and abundant materials: limestone and clay (or shale). Very precise proportions of these two basic materials have to be mixed with some additions to create a raw meal with a precise chemical composition; this will result in the production of clinker through the complex pyroprocessing presented in Figure 3.1.
