Mineralogical and Microstructural Evolution Review

Published

Author(s)

Kenneth A. Snyder

Abstract

The mineralogical and microstructural changes that occur in cementitious systems during hydration are summarized. The discussion concentrates on changes that may occur in iso-thermal systems that do not interact with the environment. The discussion includes the composition of the constituent materials, the hydration products, the pore solution composition, and the microstructural changes that may occur. The microstructural and mineralogical changes that occur during degradation reactions are discussed in general. For relevance to nuclear applications, various cementitious systems are considered. These include systems having a broad range of proportions of cement, fly ash, slag, and silica fume. Moreover, the possible effects of waste stabilization, through incorporation into the mix water, are discussed.
