Chemo-Mechanical Analysis of Adobe Minerals
- Materials Science
Archaeological adobe structures have withstood time and the elements, despite being unfired and non-cementitious mud blocks. The relative durability of adobe prompts an investigation of its structural-mechanical relationships. However, the material’s heterogeneity makes it difficult to characterize in bulk. Thus, this project deconstructs the adobe into its constituent minerals so that they may each be studied, and the components can later be used to create more complex models. Its methodology replicates a previous study, which characterized aragonite, both as a geological mineral and as nacre tablets. This project uses XRD to determine the minerals present in archaeological adobe and studies their mechanical properties using Raman Spectroscopy in a methodology known as piezo-Raman.
