介绍和对比了GB/T 26566—2011《水泥生料易烧性试验方法》和拉法基K1450易烧性指数法的测试方法和评价体系，并采用K1450易烧性指数法对中国北方地区26条生产线中水泥生料的易烧性进行了测试和评价，同时研究了率值对水泥生料易烧性的影响规律.结果表明：GB/T 26566—2011方法有待进一步改进和完善，而K1450易烧性指数法更为便捷、直观和实用，在一定程度可作为GB/T 26566—2011方法的补充；中国北方地区26条生产线中水泥生料的易烧性指数平均值为76，其中15%生产线的水泥生料易烧性被评价为“很好”，42%和31%被分别评价为“较好”和“一般”，12%被评价为“差”；率值对水泥生料的易烧性影响较大，石灰饱和系数（KH）、硅率（SM）的升高使1 450 ℃时液相量减少，离子扩散速度降低，致使水泥生料易烧性变差；铝率（IM）的增加主要导致液相黏度升高，从而降低了C3S的反应速率；相比SM和KH，IM对水泥生料易烧性的影响较小.
The evaluation methods between GB/T 26566—2011“Test method for burnability of cement raw meal” and Lafarge K1450 burnability index method are compared. Lafarge K1450 burnability index method is used to test and evaluate the burnability of cement raw meal for 26 production lines in Northern Regions of China. The influence law of cement raw meal rate value is also discussed. The results show that the GB/T 26566—2011 method still needs to be further improved， and the K1450 burnability index method is more convenient， which is a good supplementary for the GB/T 26566—2011 method. The average burnability index of cement raw meal is 76， of which 15% production lines are evaluated as “excellent”， 42% are “good”， 31% are “middle” and 12% are “poor”. The rate value has a great influence on the burnability of cement raw meal. Burnability of cement raw meal will get worse when lime saturation coefficient （KH） and silicon rate （SM） increases， which leading to the liquid content and ion diffusion velocity will be reduced at 1 450 °C. The liquid viscosity will be increased as aluminum rate （IM） increasing， and the reaction speed will decrease. Comparing with SM and KH， the impact of IM on the burnability of cement raw meal is lower.
