Accuracy in cement hydration investigations: Combined X-ray microtomography and powder diffraction analyses

Abstract

Cements are multi-phase materials that can be well understood using a multi-technique approach. Furthermore, the hydration of cement pastes is a very complex set of processes. In this work, we focus on the accuracy of the results of the laboratory computed tomography (µCT) analysis by quantifying three sets of components based on their attenuations: porosity, hydration products (HP) and unhydrated cement phases (UHP), and comparing with laboratory X-ray powder diffraction data (LXRPD).Universidad de Málaga.
