MORPHOLOGY AND MICROSTRUCTURE OF HYDRATING PORTLAND CEMENT AND ITS CONSTITUENTS. II. CHANGES IN HYDRATION OF CALCIUM SILICATES ALONE AND IN THE PRESENCE OF TRIETHANOLAMINE AND CALCIUM LIGNOSULPHONATE, BOTH WITH AND WITHOUT GYPSUM

SYSTEMATIC SEQUENTIAL OBSERVATIONS WITH THE ELECTRON MICROSCOPE WERE MADE OF THE MORPHOLOGICAL CHANGES WHICH OCCURRED DURING HYDRATION OF TRICALCIUM SILICATE AND DICALCIUM SILICATE PASTES, IN OR OUT OF THE PRESENCE OF GYPSUM. THE SPECIFIC EFFECTS OF EACH OF TWO ADMIXTURES WERE STUDIED: TRIETHANOLAMINE AND CALCIUM LIGNOSULPHONATE. WATER TO TRICALCIUM SILICATE OR DICALCIUM SILICATE RATIO WAS 0.5 AND ADMIXTURE DOSAGE WAS 0.5%. THE ADMIXTURES HAD SOME EFFECT ON CHANGES IN MICROSTRUCTURE, BUT THEY HAD A PRONOUNCED INFLUENCE ON THE RATE OF THE HYDRATION PROCESSES. /AUTHOR/
