Abstract

Many cultural heritage sites suffer from damage induced by salt crystallization in natural materials such as sandstone, both on its surface and interior. Key questions in predicting and mitigating damage due to salt remain open due to the complex interactions between the transport of salts with moisture in the interior of such materials, and the salt precipitation that can itself affect further transport. To understand when and where salt precipitates in porous materials, this project combines accelerated weathering experiments, high-resolution X-ray tomography imaging (micro-CT) and numerical simulations, where detailed experimental data serve to help formulate a computationally efficient pore-network model. By considering the controlling factors, including the pore distribution of the material and environmental conditions, this model aims to provide a novel method to predict and design remediation of salt damage in cultural heritage applications.
