Effect of temperature on the hydration of the main clinker phases in Portland cements: Part I, Neat cements
The hydration of two Mexican Portland cements has been investigated at five temperatures in the range from 10 to 60 degree C. Samples were tested after eight periods of hydration during which they were immersed in water for between 1 day and 360 days, using quantitative X-ray diffraction, thermogravimetry, compressive strength determination, and scanning electron microscopy. Increased temperature initially accelerated the hydration of the four major anhydrous phases present in both cements. In the longer term, however, a reduced degree of hydration was observed for the alite and ferrite phases, accompanied by decreased compressive strength and increased apparent porosity.
