✦ Synopsis

The possibilities to determine AFt-(ettringite) and AFm-(monosulphate) in hydrated cement pastes were studied by measuring the intensities of the pertinent DTA and XRD peaks on 4 synthetic AFt preparations, 5 synthetic AFm preparations and on a series of portland cement pastes of different composition and hydration time. For AFt determination the DTA method appears to be most suitable. AFm may be determined with any method at best semiquantitatively.
