Abstract :The purpose of this research is to ascertain the radiation, mechanical, and physical characteristics of self-compacting concrete with barite aggregate that has been prepared with various additives. Experiments were carried out on self-compacting heavy concrete samples produced using different additives to determine their physical and mechanical properties such as V-funnel, slump-spreading, collapse, compressive strength, air gap, density values of the samples, and radiation shielding values. The highest linear attenuation coefficient was 0.2859 cm⁻¹, observed in the concrete sample with CNT 4 additive. The lowest value (0.2775 cm⁻¹) was measured in the sample containing CNT 2. For CNT 1 and CNT 3, the linear attenuation coefficients were recorded as 0.2794 cm⁻¹ and 0.2818 cm⁻¹, respectively. Among the polycarboxylic ether-based additives, CNT 3 demonstrated the best radiation shielding properties.
