Utilization of bio-modified concrete composites for gamma radiation attenuation through recycled bone integration

Abstract

The potential of recycled bone ash as a sustainable additive for gamma radiation shielding concrete was explored. Concrete specimens were formulated with varying bone ash concentrations, and their efficacy in radiation mitigation properties were assessed “using Phy-X/PSD software”. A control mix (A) was prepared with a cement:sand:granite ratio of, (1 kg) and (0.5 kg), and (1 kg). Bone ash was introduced in experimental mixes (B, C, and D) at levels of (0.05 kg) and ' (0.1 kg), and (0.15 kg)', In sequence, while adjusting cement content to maintain a constant total aggregate mass. If the ratio of water to cement is fixed at 0.5 consistently applied. Density measurements indicated a reduction in density from ' (2.33 g/cm³ (A), until Sample (2.22 g/cm³ (D)', with increasing bone ash. The linear attenuation coefficient in this study (LAC) was found to be 0.662 MeV showed a corresponding decrease, with values ranging from ' (0.181 cm⁻¹ (A)' The sample' (0.171 cm⁻¹ (D)'. This study contributes to the investigation of waste valorization for radiation shielding applications and underscores the need for continued research into locally sourced materials to achieve sustainable waste management goals.
