Simulation of ultra-high-performance concrete mixed with hematite and barite aggregates using Monte Carlo for dry cask storage

Minerals, for instance barite and hematite, absorb -rays better than silica aggregates because of their higher density. The use of these minerals as main component in ultra-high performance concretes (UHPCs) exhibit promising results and enhances the toughness of an ideal radiation absorber for nu...
