THE CANNERO CASTLE (ITALY): DEVELOPMENT OF RADIOCARBON DATING METHODOLOGIES IN THE FRAMEWORK OF THE LAYERED DOUBLE HYDROXIDE MORTARS

摘要

The mortar samples of the Castle of Cannero (Lake Maggiore, Italy) have been characterized and radiocarbon (C-14) dated. The presence of LDH phases was identified. The hydraulic reaction was evaluated by a multi-analytical approach. Careful extraction, preparation and purification of the binder fraction have been performed. Contaminations due to LDH phases have been removed allowing reliable absolute dating of the structures.
