Autoclaved Cement-Quartz Pastes with Metakaolin Additions
Metakaolin (MK) additions to cement-quartz pastes autoclaved at 180°C affect the binding material and physical properties. At MK additions of up to 12%, the amount of tobermorite formed decreases when cement is partially replaced, whereas the opposite effect is observed in the case of partial replacement of quartz. An overall decrease in both compressive strength and drying shrinkage occurs with MK additions. In autoclaved systems, MK provides a source of silica that is more reactive than ground quartz.
