The Effect of Mineral Pigments on the Compressive Strength of Colored Concrete by Focusing on the Role of Improved Color Palette in Current Cities of Iran

In the civil engineering industry, concrete is a material that is widely used and highly significant. </em>The production of colored concrete has also been considered in recent decades as one of the emergent research projects in the desired industry. Using colored concretes in prominent urban structures, besides adding the desired resistance to usual concrete and other materials, play an important role in improving the urban`s color palette and the visual richness of urban environments. This study aims to investigate the effect of mineral pigments on the compressive strength of colored concrete by focusing on the role of the improved color palette in current cities of Iran. For this purpose, the samples of colored concrete with 2, 4, and 6% pigments compared to ordinary concrete were tested. The research results showed that the percentage increase in the strength of colored pigmentation of concrete samples compared to the usual concrete was 2.3%, 4.9%, and 8%, respectively, which emphasizes the strength and rigidity of colored concrete to be used in urban structures.</em>
