Bags of cement routinely have health and safety warnings printed on them because not only is cement highly alkaline, but the setting process is exothermic As a result, wet cement is strongly caustic (pH = 135) and can easily cause severe skin burns if not promptly washed off with water

Cement kiln Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silicabearing minerals to form a mixture of calcium silicatesOver a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant

Cement kiln Wikipedia

Plants that burn waste fuels enjoy a negative fuel cost (they are paid by industries needing to dispose of materials that have energy content and can be safely disposed of in the cement kiln thanks to its high temperatures and longer retention times) As a result, the inefficiency of the wet process is an advantage—to the manufacturer

Cement Extraction and processing | Britannica

Cement Cement Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary Some deposits are mined by underground methods Softer rocks such as chalk and clay can be dug directly by excavators
