Abstract

A range of advanced imaging techniques have been brought together to provide a comprehensive picture of cement microstructure for nuclear waste immobilization. Image analysis of Nirex Reference Vault Backfill (NRVB) has been used to characterize the Calcium-Silicate-Hydrate (C-S-H) matrix fraction. Through weight loss measurements and digital image correlation of OPC-based cement blends we have quantified the development of microstructure surface strains during the initial 48 hrs hardening period. The build-up of displacements on the microstructure scale indicated grain-like compressive areas, surrounded by a network of tensile regions. Serial sectioning of NRVB using ultra-microtome cutting has been explored for advanced high-resolution 3D microstructure characterization, while X-ray Computed Tomography (XCT) has been used to obtain information of the 3-D pore space and size distribution of air pores in NRVB non-destructively.
