HYDRATION OF MIXTURES OF C12A7 AND GRANULATED BLASTFURNACE SLAG

Mixtures of c12a7 and ground granulated blastfurnace slag develop high early strength and produce a fast setting cement. At 50 deg c the strength of the 1:1 mixture does not show any reduction at least up to 60 days although the 'conversion' of the initial calcium aluminate hydrates to the 'cubic' c3ah6 takes place. The hydration chemistry of these cementive mixtures has been studied by conduction calorimetry and x-ray diffraction. It appears that the formation of the compound c2ash8 may be related to the good strength properties of these cements at higher than ambient temperatures.(a)
