Abstract:
Structural colored concrete is a material which offers differentiated beauty patterns, breaks the monotony of structures, and can be more economical as a surface finish choice. Studies related to this kind of special concrete are innovative because there is both a lack of research and sparse bibliography on this subject, particularly in connection with durability. The influence of pigments on concrete properties and durability is still a question of discussion and research. In fresh concrete, the pigment characteristics can affect mixture workability. In hardened concrete, pigments can affect compressive strength, and there is not enough information in relation to color stability and durability. This research covers colored concretes with red, black, and yellow pigments (iron oxides) compared with standard concrete. Their performance related to color stability and surface changes, physicomechanical properties and some traditional durability parameters. The conclusion shows that this kind of concrete can perform well if some care is taken.
