CX-020782: Enhanced Characterization of Concrete Mineralogy using Multi-Modal Tools – Board of Trustees of the University of Illinois

The Board of Trustees of the University of Illinois, in collaboration with the University of Tennessee – Knoxville (UTK) and Oak Ridge National Laboratory (ORNL), proposes to investigate the effects of radiation exposure, via ion irradiation, on stress fractures in samples of concrete. The chemical nature and mineralogical characteristics of the aggregate directly influence the extent of radiation induced volumetric expansion (RIVE). Concrete samples will be prepared at the University of Illinois Urbana-Champaign (UIUC), irradiated at UTK, and analyzed at both UIUC and ORNL. The tasks associated with this project are (1) Improve the spatial resolution of inputs to MOSAIC; (2) Validate the outputs from MOSAIC and address any discrepancies between predicted output and experimental data; and (3) Evaluate the response of concrete to a wide radiation energy spectrum. Existing laboratory facilities will be used.
