Clinker - Clinker is benign and sintered at 1450 degrees Celsius of rock - clay, oysters and one of the different things - Its composition and yours. - 04 major oxides in the text when calcined 1450 degrees Celsius, could be the future and 4 4, while clinker C3S (3CaO. SiO2); C2S (2Cao.SiO2); C3A (3CaO.Al2O3); C4AF (4CaO. Al2O3. Fe2O3) Our equipment can be used in the best way. Components of Clinker software: CaO = 62 - 68% SiO2 = 21 - 24% Al2O3 = 4 - 8% Fe2O3 = 2 - 5% There are also some other oxides in small amounts: MgO, Na2O, K2O (MgO content
