Optimization and evaluation of structural and shielding concrete for IFMIF-DONES
Abstract:
The aim of this study was to optimize and evaluate structural and shielding concrete for the IFMIF-DONES
building. An ordinary concrete of lime-dolomite aggregate from local sources has been chosen for structural
concrete and magnetite aggregate was chosen for heavy-weight radiation shielding. The reference for concrete
materials design was the one used in the ITER project. After investigations of raw materials, a group of pre-
batches were prepared and technical properties – density of compressive strength, were measured. Finally, two
compositions have been elaborated – one for structural concrete of density 2.5 g/cm$^3$ and the second for radi-
ation shielding concrete of density 3.9 g/cm$^3$. Then a set of 50 × 50 × 5 cm$^3$ slabs were prepared and sent to the
Nuclear Physics Institute of the CAS in the Czech Republic for shielding mock-up experiments. Also the other
technical properties like E-modulus, bending strength etc. have been determined. Additionally, radiation
shielding efficiency has been calculated based on atomic composition.
