INFLUENCE OF QUARTZ ON THE HYDRATION OF 3 CAO. AL203
QUARTZ IS FOUND TO INTENSIFY THE HEAT EVOLUTION PEAK IN 3 CAO.AL203-WATER PASTES CONNECTED WITH CONVERSION OF HEXAGONAL INTERMEDIATE HYDRATES INTO THE FINAL PRODUCTS /CUBIC 3 CAO.AL203.6H20 AND HYDROUS ALUMINA/. CHEMICAL ANALYSES OF THE LIQUID PHASE IN SUSPENSIONS OF 3 CAO.AL203 IN WATER IN THE ABSENCE AND IN THE PRESENCE OF QUARTZ ARE AT A VARIANCE WITH A MECHANISM INVOLVING A CHEMICAL ACTION OF QUARTZ, AND INDICATE THAT THE QUARTZ PARTICLES ACT AS PRECIPITATION SITES FOR HYDROUS ALUMINA. HEAT EVOLUTION DATA ARE CONSISTENT WITH AN ANALOGOUS ACTION IN PASTES. /AUTHOR/
