This study examines the impact of replacing up to 5 vol% of Portland cement (PC) with both pristine mixture of Bi2O3/Gd2O3 (BG) and silica-coated BG particles. Two different types of silica coatings, each with varying synthesis methods, were applied to coat the BG structures, and their impact on the fresh, hardened, microstructure and radiation-shielding performances of the 3D printed...
