MORPHOLOGY AND MICROSTRUCTURE OF HYDRATING PORTLAND CEMENT AND ITS CONSTITUENTS; III, CHANGES IN THE HYDRATION OF A MIXTURE OF TRICALCIUM SILICATE, TRICALCIUM ALUMINATE, AND GYPSUM WITH AND WITHOUT TRIETHANOLAMINE AND CALCIUM LIGNOSULPHONATE PRESENT

THIS IS THE THIRD PAPER IN A CONTINUING SERIES WHICH STUDIES THE MORPHOLOGICAL CHANGES OCCURRING DURING THE HYDRATION OF PORTLAND CEMENT AND ITS PURE COMPONENTS IN THE ABSENCE AND IN THE PRESENCE OF ADMIXTURES. THE OBJECT OF THESE INVESTIGATIONS IS TO IMPROVE THE UNDERSTANDING OF THE NATURE OF MORPHOLOGICAL CHANGES MECHANICAL PROPERTIES OF PASTE AND CONCRETE. IN THIS RELATE MICROSTRUCTURE OF CEMENT PASTE TO PHYSICAL AND MECHANICAL PROPERTIES OF PSTE AND CONCRETE. IN THIS STUDY, SYSTEMATIC SEQUENTIAL OBSERVATIONS WITH THE ELECTRON MICROSCOPE WERE MADE OF THE MORPHOLOGICAL CHANGES WHICH OCCURRED DURING THE HYDRATION OF A PASTE MIXTURE OF TRICALCIUM SILICATE, TRICALCIUM ALUMINA, AND GYPSUM. IT WAS FOUND THAT THIS SYSTEM PRODUCED HYDRATION PRODUCTS SIMILAR IN NATURE TO THOSE PRODUCED BY THE MONOMINERAL SYSTEMS WITH GYPSUM PRESENT. THE TWO ORGANIC ADMIXTURES STUDIED HAD SOME EFFECT ON CHANGES IN MORPHOLOGY AND MICROSTRUCTURE OF THE HYDRATING MIXTURE, BUT THEY SHOWED A PRONOUNCED INFLUENCE ON THE RATE OF THE HYDRATION PROCESSES. /CCR/
