THE HEATS OF HYDRATION OF TRICALCIUM SILICATE AND BETA- DICALCIUM SILICATE

TRICALCIUM SILICATE HYDRATES AT 23 C BY REACTING WITH THREE MOLES OF WATER PER MOLE, AND BETA-DICALCIUM SILICATE REACTS WITH TWO MOLES OF WATER PER MOLE. WHEN THE HYDRATION REACTIONS TAKE PLACE IN THE FORM OF HARDENED PASTES AT ROOM TEMPERATURE, WITH A WATER-TO-SOLID RATIO OF 0.7 BY WEIGHT, THE CHANGES IN HYDRATION HEAT ARE GIVEN. EVIDENCE IS PRESENTED THAT IN THE HYDRATION OF THE TWO SUBSTANCES THE SAME CALCIUM SILICATE HYDRATE IS PRODUCED. /PCA/
