Detailed interpretation of results obtained for calcium
aluminate cement pastes is difficult because of complexity
of composition of studied samples. The processes of
dehydration of individual compounds overlap. Multistage
decomposition of some hydrates may cause arising of
compounds that also may be expected in hydration products
of the cement. Moreover temperatures of decompositionsfor particular hydrates, like in the case of other compounds,
depend on their degree of crystallinity, mass of sample,
conditions of measurements, gas atmosphere, etc. It
explains different temperature ranges that are found in
literature and ascribed to presence of specific phases. Thus,
thermal analysis results should be discussed only as estimated
analysis of composition of aluminate cement pastes.
However, it does not change the fact, that thermal analysis
is often applied by a lot of researches and obtained results
may be helpful especially in comparative analysis of
influence of additives on hydration process.
