【摘要】 针对高C3S熟料矿物体系,研究了BaO对相应的高钙生料易烧性的影响,并通过XRD、SEM研究了熟料矿物的结晶状况。结果表明:在较低烧成温度下(≤1350℃),掺入适量BaO后,能较明显地改善生料的易烧性,对矿物结晶影响不明显;但是在较高烧成温度下(>1350℃),掺入BaO对改善生料的易烧性不利,C3S结晶程度下降,晶体尺寸均匀性降低。另外还对BaO影响高钙生料易烧性的机制进行了探讨。更多还原

【Abstract】 The effect of BaO on the calcinations of high C₃S clinker was studied and some primary mineral phases components,crystallization and morphology were analyzed by the glycol-ethanol method,XRD and SEM.The results show that for high C₃S clinker suitable BaO content is in favor of the clinker burning and accelerates the formation of C₃S at lower temperature（≤1350℃）;but at higher temperature（>1350℃） BaO has adverse effects——it prevents the clinker burning and hinders crystallization and growth of C₃S with the BaO contents increasing.The cause of the different effects at higher and lower temperature is discussed.更多还原
