摘要

In this paper a comparative study of the hydration process in a very early age, first 20 hours, between a conventional cement paste and its equivalent with a replacement of fly ash of about 7.9%, is done. The study was undertaken through semiadibatic calorimetry, electrical impedance spectroscopy and X-ray diffraction. It shows that using electrical impedance spectroscopy we can determine the state of crystallization of the material with and without additions, thereby determining the time at which the different processes are started in the hydration
