THE HYDRATION OF TRICALCIUM SILICATE AND BETA DICALCIUM SILICATE AT ROOM TEMPERATURE

IN THE ROOM TEMPERATURE HYDRATION OF TRICALCIUM SILICATE AND BETA DICALCIUM SILICATE THE HYDRATION PRODUCTS ARE A CALCIUM SILICATE HYDRATE AND CALCIUM HYDROXIDE. SOME OF THE PROPERTIES OF TRICALCIUM SILICATE, DICALCIUM SILICATE, CALCIUM HYDROXIDE AND THE AQUEOUS PHASE ARE PRESENTED, AND THE CHEMICAL AND PHYSICAL PROPERTIES OF THE CALCIUM SILICATE HYDRATE ARE DISCUSSED IN CONSIDERABLE DETAIL. THIS HYDRATE IS A MEMBER OF A SERIES OF HYDRATES, CALLED TOBERMORITES. THE PROPERTIES OF OTHER TOBERMITES ARE DISCUSSED IN RELATION TO THOSE OF THE TOBERMORITES PRODUCED IN THE HYDRATION OF TRICALCIUM SILICATE AND BETA DICALCIUM SILICATE. DATA ARE GIVEN ON THE HEATS OF HYDRATION OF TRICALCIUM SILICATE AND DICALCIUM SILICATE AND ESTIMATES ARE MADE OF THE ENTROPIES AND FREE ENERGIES OF HYDRATION. FINALLY, THE RATES AND MECHANISMS OF HYDRATION ARE DISCUSSED. /PCA/
