MORPHOLOGY AND MICROSTRUCTURE OF HYDRATING PORTLAND CEMENT AND ITS CONSTITUENTS. I. CHANGES IN HYDRATION OF TRICALCIUM ALUMINATE ALONE AND IN THE PRESENCE OF TRIETHANOLAMINE OR CALCIUM LIGNOSULPHONATE

MORPHOLOGICAL CHANGES WHICH OCCUR DURING THE HYDRATION OF TRICALCIUM ALUMINATE PASTE WERE OBSERVED BY ELECTRON MICROSCOPY FROM THE AGE OF 5 MINUTES TO 3 MONTHS. X-RAY ANALYSES WERE USED TO IDENTIFY PHASES. THE EFFECTS OF THE ADMIXTURES, TRIETHANOLAMINE AND CALCIUM-LIGNOSULPHONATE WERE INVESTIGATED WITH AND WITHOUT GYPSUM. THE DOSAGE OF ADMIXTURE WAS 0.5%; THE WATER TO TRICALCIUM ALUMINATE RATIO WAS 1.0. THE RESULTS SHOWED CLEARLY THE MORPHOLOGICAL CHANGES THAT TOOK PLACE AS HYDRATION PROCEEDED, AND SHOWED THE SPECIFIC INFLUENCES OF EACH OF THE TWO ADMIXTURES. /AUTHOR/
