The material characterization and gamma attenuation properties of Portland cement-Fe3O4 composites for potential dry cask applications

The effect of nanosized magnetite (Fe3O4) additions on the microstructural, mechanical and gamma attenuation properties of White Ordinary Portland cement (WOPC) pastes was investigated. The microstructure of a set of cement composites with Fe3O4 content ranging from 0 to 50 wt% was examined using X-...
