Количественный фазовый анализ цементного камня методом Ритвельда на стадии твердения

Abstract

The article presents the results of the quantitative research phase content in the cement stone by the Rietveld method on the curing stage in the range of 6 − 61 hours at temperatures of 40, 50, 70 °C. It was found that the major phases include test cement stone Tobermorite, Deliate, mCanH2O10Si2, where m = 5 or 3 and n = 3 or 1. Phase content was evaluated on the contribution of the individual phases in the integrated intensities calculated, which in turn, is compared with the experimental diffraction pattern. There were also evaluated the mass fractions of phase gratings. Time and temperature isothermal hardening have a significant influence on the structuring of cement stone.
