摘要

Microscopical relationships between different phases in cement clinkers can be used to interpret the sequence of crystallization, that is, which crystals formed before others. This paper lists some of the observations allowing the relative determination of crystallization sequence. Periclase, for example, can be shown to occur within alite, and the latter crystal is, therefore, younger. Periclase within belite indicates the existence of periclase prior to the crystallization of belite. Free lime, belite, and matrix within alite are all older than the enclosing alite. Aluminate (C3A) can be shown to be younger than the adjacent ferrite, but the opposite relationship might apply under different conditions of cooling. These and other examples are selected to illustrate relative age relationships between some of the crystals occurring in portland cement clinker.rnThe subjects of crystallization from a solution or melt, or growth within the solid state, lie at the heart of physical chemistry. Interesting and fundamental as they are, they are beyond the scope of this presentation. The effects of minor elements and gases (fluorine , sulfate, and oxygen levels, for example) or other crystal-chemistry relationships make generalizations about clinker-crystal sequence somewhat speculative. I believe, however, that the microscopical criteria for determination of crystal sequence remain applicable, tempered with an understanding of their possible fallibility.
