Abstract
Provided is a method for controlling a free lime content of a clinker by regulating the free lime content. Here the amount of sulfur trioxide resulting from fuel and the used amount of a fluorine-based mineralizer are regulated using the following Formulas (1) to (3), thereby controlling the free lime content (f.CaO) of the clinker.f.CaO=0.29×e(×SO)  (1)  (2)  (3) SOis an amount of sulfur trioxide in the clinker; a is a coefficient satisfying Formula (2); b is a coefficient satisfying Formula (3); F is an amount of fluorine in the clinker; when a burning temperature is X° C., t=X/1450; and HM is a hydraulic modulus.
