摘要： PROBLEM TO BE SOLVED: To provide a determination method of abnormal setting retardation of ordinary portland cement which can determine before using the cement whether mortar and concrete made by adding three times the amount of a retarding type AE water-reducing agent than the amount predetermined by a manufacturer induce the abnormal setting retardation or not.
SOLUTION: Cement is determined acceptable when the final setting time of mortar is equal to or less than 35 hours, in tripling the amount of a LS based retarding type AE water-reducing agent added to ordinary portland cement compared to the amount predetermined by the manufacturer, and determined unacceptable when exceeding 35 hours. It is therefore determined before using the ordinary portland cement whether the cement does not induce the abnormal setting retardation without taking various measures for accelerating setting such as warming the mortar and concrete even when three times the amount of the retarding type AE water-reducing agent than the amount predetermined by the manufacturer is added.

摘要： PROBLEM TO BE SOLVED: To provide ordinary portland cement preventing abnormal retardation of setting, which does not cause abnormal retardation of setting, even by adding an AE (air entraining) water-reducing and retarding admixture in an amount 3-times larger than that designated by the manufacturer.
SOLUTION: The portland cement has a total SO
3 content of 2.0-3.0 wt.%, wherein the amount of SO
3 added in the form of gypsum etc. is ≥0.9 wt.%, and mortar sets within 35 hr when adding the AE water-reducing and retarding admixture in an amount 3-times larger than that designated by the manufacturer. Therefore, the portland cement does not cause abnormal retardation of setting without taking various measures for promoting the setting, such as heating of the mortar or the cement, even when adding the AE water-reducing and retarding admixture in an amount 3-times larger than that designated by the manufacturer.

摘要： PROBLEM TO BE SOLVED: To provide cement clinker which necessitates no considerable change in main chemical components of cement, is free from pre-heater coating troubles and adverse influences on cement properties and is effective in reducing the quantity of heat required for firing. SOLUTION: In the process for cement clinker production, cement, cement clinker or refractory brick having a melting point higher than the temperature of a liquid phase of the cement clinker and serving as crystal nuclei for alite is charged into a kiln from the kiln inlet or the front part of the kiln.

摘要： PROBLEM TO BE SOLVED: To provide a cement clinker capable of reducing MgO periclase in a cement clinker containing a prescribed amount of MgO, and to provide its manufacturing method.
SOLUTION: When the amount of Mg increases and exceeds 2% in a raw material of cement, periclase is formed. Periclase degrades a cement hardened body. Therefore, barium is added based on a relational expression between MgO and BaO in the raw material of the cement. When Ba exists simultaneously with Mg, both ion radii are averaged and brought close to Ca because Ba has a large ion radius of 136 pm. As a result, the amount of Mg capable of forming solid solution in cement minerals is increased and the formation of the periclase can be prevented.

Examples of the substance to be incorporated include a fine powder of a refractory brick, particles of an ordinary portland cement clinker, a fine powder of a high-early-strength portland cement clinker, a high-early-strength portland cement, and a fine powder of quick lime. As a result, alite generation is accelerated even at a low temperature. As a result, a high-quality clinker can be produced through firing using a small unit quantity of heat. No decrease in cement quality results. As a result, the process contributes to a reduction in pre-heater coating amount and prolongation of the life of the refractory bricks.
