Structural performance and radiation shielding of low-carbon heavyweight geopolymer concrete with barite aggregate

Heavyweight geopolymer concrete (GPC) was developed by replacing conventional limestone coarse aggregate with barite (BR) at 0–100% by volume. The resulting composite achieved a density of up to 3167 kg/m3 and demonstrated significant improvement in radiation shielding, with a 35% increase in gamma-...
