Paper Title:
Research on Hydration Mechanism of 50% Portland Cement–50% Fly Ash Systems with TA and NMR Techniques
  Abstract

In this article, research on hydration mechanism of 50% Portland cement–50% fly ash(FA) systems has been carried out with TAM AIR Isothermal Calorimete (TA) and 29Si nuclear magnetic resonance(NMR) spectroscopy. The research was including hydration heat liberation behavior and nanostructure of C-S-H gel in hydrated cement systems. The addition of fly ash could observably reduce the total hydration heat and the mean chain length (MCL) of C-S-H gel was found to be and respectively for 7-day-old and 28-day-old.
