The density and compressive strengths of concrete are depicted in Fig. 8 and Fig. 9. From these figures, the normal concrete had a density of 2,374 kg/m 3, while the barite concrete had a density of 3,340 kg/m 3. The 7-day and 28-day compressive strengths of barite concrete were slightly larger than those of normal concrete.

Delanvaz's [55] study found that the gamma-ray attenuation coefficient of concrete with an apparent density of 2.36 g/cm³ is 0.18 cm⁻¹, whereas barite concrete with an apparent density of 3.261 g/cm³ has an attenuation coefficient of 0.28 cm⁻¹. These results are generally consistent with our findings.
