摘要：

In order to reveal the effect of fly ash on the microstructure evolution of cementitious materials under steam curing comprehensively, the chemically bonded water of the pastes containing FA were tested, and the corresponding morphologies were also determined by scanning electron microscopy (SEM). The results indicate that the steam curing can activate the pozzolanic reaction of FA, especially early ages, and the paste containing FA under steam curing can produce more hydration products compared to the paste containing FA under standard curing. However, the steam curing also degrades the pore structure of the paste. Copyright © 2016 American Scientific Publishers All rights reserved.
