| Résumé : | The work described here was carried out in order to determine the action of CaO on SiO2 by raising the temperature of mixtures of these oxides. For this, samples containing CaCO3 and amorphous SiO2, or, Ca(OH)2 and amorphous SiO2 were prepared. The formation of Ca silicates during the rise in temperature has been studied. The samples maintained 3 hours at various temperatures up to 1500° were examined by × rays and a differential thermal analysis of the mixtures was made. In order to demonstrate the formation of the various silicates (CS, C2S, C3S), it was necessary to synthesize the compounds in the pure state. I determined the × rays diagram of these silicates and compared them with the diagrams obtained by examination of the mixtures of oxides heated at various temperatures. The comparison of the results obtained has led me to propose a scheme of reaction of SiO2 on CaO in the solide state during the rise in temperature. Copyright © 1953 Wiley‐VCH Verlag GmbH & Co.
