β¦ Synopsis
C3S samples of different fineness were precured at room temperature and subsequently autoclaved. It was found that, as the fineness is increased: I) the effect of precuring on the hydration rate of C3S in autoclave is less evident; 2) the precuring 754 VoI. 4, No. 5 G. Chiocchio, M. Collepardi

The hydration of quartz-tricalcium silicate mixtures at 175Β°C has been studied. The samples, precured at 25Β°C for different periods of time, in the range 0 -16 hours, have been autoclaved for 8 hours. Upon addition of quartz to the system water-tricalcium silicate, some remarkable modifications have
Hydration of C3S in salt solutions having ions in common with its hydration products was investigated by calorimetry and aqueous phase analyses. Soluble calcium salts, which depress hydroxyl ion concentrations in solution by promoting Ca(OH) 2 precipitation, were observed to accelerate hydration. Ac
In his stimulating discussion (1) of our paper, (2) Dr. Skalny claims that some disagreement exists between our data and those obtained by himself (3)(4)(5) and by other authors. (6'7) We will try to demonstrate that, taking into account the analytical methods available, the results are in good agre
