Ageing of Clay-Based Materials

Abstract:

One of the general symptoms of ageing is a volume change due to the moisture exposure, known as an irreversible moisture expansion (IME). It is assumed IME of fired clay-based materials is governed by the presence of inner-surface and interlamellar OH-groups, present in clay minerals and assumed to be also abundant in amorphous intergranular phases. IME was measured on a series of clay-based ceramic bodies with a variable content of clay raw minerals under two different hydrothermal conditions. IR spectroscopy was used to correlate IME with the increasing amount of inner and interlamellar hydroxyl groups.
