✦ Synopsis

The effect of gypsum on the early stages of C3S hydration is explored by means of DTA, high-resolution STF~I, and liquid phase studies.

Literature data show that substantial amounts of sulfate ion can be incorporated in the structure of C-S-H, the main product of C3S hydration (1-5). During hydration of the C3S + C3A + gypsum system, calcium silicoaluminates may form which are similar to sulfate-containing AFt and AFm phases (6). To better understand both the effect of gypsum on cement hydration and the morphology of the hydration products, studies on C3S hydration in the presence of gypsum were incorporated into a mechanistic study of cement hydration.

Composite materials were prepared from C3S and 12% (I) vinyl sulfonic acid (2) p-styrene sulfonic acid. The hydration of the composite systems were compared to that of neat C3S for different ages up to 90 d, by DTA-TG, IR and XRD. The polymers were found to retard the hydration of the silicate due t
