Abstract: Cement manufactured by using a gap phase of a controlled clinker is provided to reduce an exhaust of carbon dioxide, to save energy and to protect environment by reducing a fuel-used quantity and using lime stone having lower quality. Cement is manufactured by synthesizing a clinker of which a lime saturation factor(LSF) is 91 and an A/F ratio(aluminate to ferrite) is 0.15~0.30 or the LSF is 90 - 85, a silica modulus is over 2.5, an iron modulus is below 1.5 and the A/F ratio is 0.15~0.30. An SO3 content of the clinker is controlled to 0.5~1.0 weight%.
