AB - Recently, as there has been growing demand for aesthetic quality in structural materials, the development ofexcellent color cement concrete having good coloration properties has become a requirement. This study is designed toanalyze the basic physical properties of mortar and the properties of keeping the coloration under an ultraviolet rayaccelerated weathering test environment according to changes in the mixing ratio between carbon black and iron oxide usedas colorants. The test results show that the use of carbon black and iron oxide reduces the initial flow by 6.3~17.2 % andthe air content by 3.5~31.5 % but increases the unit volume weight by 3.4~5.5 %, compared to ordinary Portland cement(OPC). In addition, the study shows that the addition of iron oxide increases the self drying shrinkage. So, caution needsto be taken on the workability of the concrete. The brightness value L*represented by black showed the most excellentblack colour when carbon black 3 % and iron oxide 5 % are added. According to UV accelerated weatherproof test, thebrightness value L*was found to increase in all experiment specimens by 4.28~11.97 %, and the color change by UV wasfound to be higher for the case where carbon black colorant was not used. Therefore, in terms of color revelationcharacteristics, the case using carbon black 3 % and iron oxide 5 % was found to show the best black color
