الإسمنت أو الغضار هو المادة الرابطة الناعمة التي تتصلب وتقسى فتملك بذلك خواصا تماسكية وتلاصقية بوجود الماء مما يجعله قادرا على ربط مكونات الخرسانة بعضها ببعض. وأهم استخدام للأسمنت هو الملاط والخرسانة حيث يربط المواد الاصطناعية أو الطبيعية لتشكل مواد بناء قوية مقاومة للتأثيرات البيئية العادية. يجب عدم الخلط بين الخرسانة 

Rawmill Wikipedia

A rawmill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill. The rawmilling stage of the process effectively defines the chemistry (and therefore physical 

Cement kiln Wikipedia

Over 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. As the main energyconsuming and greenhousegas–emitting stage of cement manufacture, improvement of kiln efficiency has been the central 

Portland cement Wikipedia

To achieve the desired setting qualities in the finished product, a quantity (2–8%, but typically 5%) of calcium sulfate (usually gypsum or anhydrite) is added to the clinker, and the mixture is finely ground to form the finished cement powder. This is achieved in a cement mill. The grinding process is controlled to obtain a
