Baryte Concrete

Shielding

Density: 3.35 g/cm³

High-density concrete using baryte (BaSO₄) aggregate. Enhanced gamma-ray shielding compared to ordinary concrete due to high-Z barium content.

Notes

Higher density than ordinary concrete provides better gamma shielding. Lower hydrogen content reduces neutron shielding effectiveness compared to ordinary concrete.
