PROBLEM TO BE SOLVED: To provide a cement clinker capable of being fired at a temperature of 1,300 to 1,400°C being lower compared with the conventional one and also having physical properties in strength properties such as mortar compressive strength.SOLUTION: Provided is a cement clinker in which the total content of CA and CAF calculated according to a Bogue equation is 22% or higher, the CS content is 60% or higher, and also, an iron modulus (I.M.) is 1.3 or lower, preferably, 1.0 to 1.3. Since the total content of the CA and the CAF is 22% or higher, firing can be performed at low temperature, and also, deterioration in its strength can be prevented by the reduction of its iron modulus. |
