Cementframleiðsla

Cementframleiðsla refers to the industrial process of producing cement, a binder substance used in construction that sets, hardens, and adheres to other materials to bind them together. The primary raw materials for cement production are typically limestone and clay, which are quarried and then finely ground. These raw materials are mixed in precise proportions and then heated to very high temperatures, around 1450 degrees Celsius, in a rotary kiln. This process, known as clinkerization, transforms the raw materials into a nodular material called clinker. The clinker is then cooled and ground into a fine powder. Gypsum is usually added during the grinding process to control the setting time of the cement when mixed with water. Different types of cement can be produced by varying the composition of the raw materials and the grinding process, leading to cements with specific properties suitable for various construction applications. The production of cement is an energy-intensive process and is a significant contributor to global carbon dioxide emissions due to the chemical decomposition of calcium carbonate in limestone.
