Influence of foreign ions on calcium silicate hydrate under hydrothermal conditions: a review
Abstract
Cementitious materials have long been used also in hydrothermal conditions, where hydration is significantly different from ambient temperature conditions. The high temperature accelerates mineral dissolution, especially of supplementary cementitious materials (SCMs). This paper reviews the influence of the foreign ions Al 3+ , Na + , K + , Mg 2+ , Fe 3+ and SO 4 2- dissolved from SCMs and cement clinkers as well as the Ca/Si ratio on the hydration kinetics, including the formation of amorphous C-S-H and its transformation into crystalline phases, and hydrates characteristics under hydrothermal conditions. When SCMs are present under hydrothermal conditions, in addition to the physical parameters, the chemical and mineralogical compositions of the SCMs considerably influences the types and amounts of hydrates. Therefore, the compositions of mixtures can be optimised in order to control the formation rate and sequence of hydrates and their properties.
