THE REACTIONS AND THERMOCHEMISTRY OF CEMENT HYDRATION AT ORDINARY TEMPERATURE

THE EVIDENCE AVAILABLE FOR ESTABLISHING THE PRODUCTS OF PORTLAND CEMENT HYDRATION IS MAINLY INDIRECT. IT CONSISTS LARGELY OF STUDIES MADE ON THE SIMPLER SYSTEMS OF OXIDES. RESULTS OBTAINED IN THESE STUDIES ARE DISCUSSED. DETERMINATIONS OF HEAT OF HYDRATION OF PORTLAND CEMENT PASTE HAVE BEEN MADE MAINLY FOR IMMEDIATE, PRACTICAL PURPOSES, BUT COMPARISON OF THE DATA WITH VALUES FOR THE CLINKER COMPOUNDS HYDRATING SEPARATELY HAS AFFORDED SOME INDICATION OF THE CHEMISTRY. RECENT STUDIES HAVE PROVIDED DATA ON HEAT EVOLUTION OVER A 6-1/2 YEAR PERIOD. OTHER STUDIES HAVE PROVIDED EXTENSIVE NEW DATA ON EFFECT OF WATER-CEMENT RATIO. CONTINUOUS RECORDS OF THE HEAT EVOLUTION OF CEMENT PASTE DURING THE SETTING PERIOD HAVE FURNISHED INTERESTING INDICATIONS. /PCA/
