High density concrete reinforced with copper slag is studied as part of the fine aggregate to improve its mechanical properties and obtain protective barriers to attenuate ionizing radiation to acceptable levels, as well as a mixture with greater workability and homogeneity. The method used was the deductive with applied guidance and quantitative approach. The data collection instrument was retrolective, descriptive, correlational and explanatory. The design was the experimental, longitudinal, prospective and cohort study (cause-effect). A concrete with resistance pattern f ‘c = 210 kg / cm2 is designed, with 5 types of additional mixtures to be compared with the standard mixture, with different percentages of copper slag (15%, 30%, 50%, 80 % and 100%) as partial replacement of the fine aggregate. The sample consists of 144 specimens with measures 20cmx10cm, for tests of resistance to compression and tensile at ages are 3, 7, 14 and 28 days. 18 plates were also made with measures of 20cm x 20cm of variable thicknesses (1.5 cm, 2 cm, 2.5 cm), to perform direct radiationdosimetry tests exposing them to a constant intensity of X-rays. The study determined that as it increases the dosage of the percentage of copper slag increases the density of the concrete; The compressive strength and tensile strength are increased until the incorporation of 30% copper slag, after that percentage the resistance decreases gradually. In the attenuation of the ionizing radiations it was observed that the higher the percentage of copper slag, the protective barriers improve, providing greater radiological protection. The study determined that the optimal design proposal consists of the dosage of 50% copper slag and 50% fine aggregate, with a slab thickness of 2.5 cm, homogeneity degree of 2.51%, percentage of attenuation of ionizing radiation 93.28 %, density 2699.27 kg/m3, resistance to understanding 376.70 kg/cm2 and tensile strength of 30.13 kg/m3.
