Clinker is a solid material produced during the manufacturing of cement. It forms when limestone and other raw materials are heated in a kiln at high temperatures, typically around 1,450 degrees Celsius. The resulting product is then cooled and ground into a fine powder to create cement, which is a key ingredient in concrete. In construction, clinker is essential for producing strong and durable structures. It contributes to the chemical reactions that occur when mixed with water and aggregates, leading to the hardening process of concrete. This makes clinker a vital component in the building industry, influencing the quality of structures like bridges, roads, and buildings.
