CLINKER & ITS FUNCTION
Clinker is produced from the process of heating in 1500 centigrade the mined raw materials such as limestone (calcium carbonate – CaCO3) together with sand which contains Silica. Through multiple stages of production, the clinker turns into small, granulated pellets or stones, some are grey or even darker depending on the type of limestone and other secondary cementitious materials (SCM). With compositions such as Calcium oxide, Silicon Oxide, Aluminum Oxide plus Iron Oxide, Clinker serves as they key ingredient in making cement, containing 95% and some other 5% additives.
This traditional cement production is responsible for emitting CO & CO2 that are toxic and harmful elements to the atmosphere. These greenhouse gases intensify carbon footprints that lead to intensified health and environmental problems.
