摘　　要：用X—射线衍射仪对含Al_2O_3的氧化钙熟料在不同条件下放置过程中水化产物进行了鉴定;用电子探针分析了Al_2O_3等在CaO基体中的分布。结果进一步证实了这种熟料抗水化的原因在于其极低的显气孔率和发育良好CaO晶粒自身水化活性的降低。3CaO·Al_2O_3(C_3A)分布在CaO晶粒周围也起到了保护CaO晶粒免于水化的作用。With X-ray diffraction analysis, the hydrated products in the CaO clinkers containing Al₂O₃ as additive, held under diffrent conditions, were determined. The distribution of Al₂O₃, SiO₂, etc in the CaO matrix was also determined with electron scan ning probe. The observation confirms further that the good hydration-resistance of such CaO clinker is attributed to its very low apparent porosity and relatively low hydrated activity of the good crystalized grains, and moreover, the existance of 3 calcium·alumina（C₃A） around the CaO grains has some effects on protecting CaO grains from hydrating.
