The so produced cement clinker is ground together with gypsum and/or anhydrite, thus forming the final product cement. Depending on the availability of the raw materials and market-specific requirements, further extenders are added to the common grinding process such as granulated blast-furnace slag.
Cement extenders (aka Supplementary Cementitious Materials) are materials that can be used to offset a portion of the clinker in cement, without compromising performance. The use of SCMs is one of the most effective ways to reduce emissions.
These materials are blended together, either wet or dry, and fed into a rotary kiln, which fuses the limestone slurry at temperatures ranging from 2,600 to 3,000°F into a material called cement clinker.

Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties.
The clinker surface and its reactions in different electrolytic solutions are investigated by scanning electron microscope and atomic force microscopy. Uses. Portland cement clinker is ground to a fine powder and used as the binder in many cement products.

Cement Clinkers In the production of cement, clinkers are the sintered lumps exiting the cement kiln. Clinkers are typically 1 to 25 mm in diameter. Clinker materialography is commonly performed and serves three basic purposes: quality control, problem solving, and monitoring process improvements. When clinkers are examined regularly, the
