“…Primary factors attributable to this behavior are (1) surface-to-volume ratio and (2) quantum confinement effects [ 35 ]. Similarly, various comparative studies on cement-based materials have already confirmed the superiority of nanosized PbO [ 22 ], WO 3 [ 22 ] and Bi 2 O 3 [ 9 , 10 ] over coarser particles.…”

“…Therefore, various alternative material solutions are sought. To date, the highest attention has been paid to Bi 2 O 3 [ 7 , 8 , 9 , 10 ] followed by TiO 2 [ 11 , 12 , 13 , 14 ], Fe 2 O 3 [ 15 , 16 , 17 ] or WO 3 [ 18 , 19 , 20 , 21 , 22 ]. Bismuth oxide exhibits similarly high radiation attenuating properties regarding gamma radiation as lead, but is considered non-toxic.…”

This study presents a new approach towards the production of sol-gel silica-coated Bi2O3/Gd2O3 cement additives towards the improvement of early mechanical performance and radiation attenuation. Two types of silica coatings, which varied in synthesis method and morphology, were used to coat Bi2O3/Gd2O3 structures and evaluated as a cement filler in Portland cement pastes. Isothermal calorimetry studies and early strength evaluations confirmed that both proposed coating types can overcome retarded cement hydration process, attributed to Bi2O3 presence, resulting in improved one day compressive strength by 300% and 251% (depending on coating method) when compared to paste containing pristine Bi2O3 and Gd2O3 particles. Moreover, depending on the type of chosen coating type, various rheological performances of cement pastes can be achieved. Thanks to the proposed combination of materials, both gamma-rays and slow neutron attenuation in cement pastes can be simultaneously improved. The introduction of silica coating resulted in an increment of the gamma-ray and neutron shielding thanks to the increased probability of radiation interaction. Along with the positive early age effects of the synthesized structures, the 28 day mechanical performance of cement pastes was not suppressed, and was found to be comparable to that of the control specimen. As an outcome, silica-coated structures can be successfully used in radiation-shielding cement-based composites, e.g. with demanding early age performances.
