This study explored the influence of using copper slag as an alternative sand for producing cement mortar bricks and its effect on γ-ray attenuation property, strength, and consistency of mortar. The linear attenuation coefficients and mass attenuation coefficients were experimentally determined for mortar mixtures using the ⁶⁰Co and ¹³⁷Cs gamma-ray source, and, using the Phy-X program, attenuation parameters were theoretically calculated in 1 keV–100 GeV. Sample bricks with added copper slag were produced and tested. In the results, the added copper slag was greatly beneficial for increasing the flowability and strength of mortar, and, given all the results of attenuation parameters, the use of copper slag as aggregates was notably advantageous compared to silica sands for gamma-ray attenuation mainly due to the high Fe quantity in copper slag. The trial brick specimens using 100 wt% copper slag replacement for sand not only satisfied all requirements of cement brick in the Korean standard (KS) F 4004, but also the TCLP regulation.

本研究探讨了使用铜渣作为替代砂生产水泥砂浆砖的影响及其对砂浆γ射线衰减性能、强度和稠度的影响。使用⁶⁰ Co 和¹³⁷对砂浆混合物的线性衰减系数和质量衰减​​系数进行了实验确定Cs 伽马射线源，以及使用 Phy-X 程序，理论上计算的衰减参数为 1 keV–100 GeV。生产并测试添加了铜渣的样品砖。结果表明，铜渣的加入对提高砂浆的流动性和强度有很大的好处，从衰减参数的所有结果来看，与硅砂相比，使用铜渣作骨料在伽马射线衰减方面明显优于硅砂。由于铜渣中铁含量高。使用 100 wt% 铜渣替代砂的试砖试件不仅满足韩国标准 (KS) F 4004 中水泥砖的所有要求，还满足 TCLP 规定。
