Lately concrete has been used not only as backbone of structure but as esthetical construction art. The challenge is to combine these two parameters and predict concrete behaviour. The target of this paper is to successfully develop easily controllable, visually attractive concrete that provides with necessary compressive strength criteria. Two mix designs with Fe2O3 and Fe3O4 pigments were tested for 1, 3, 7, 14, 28-day compressive strength. Concrete samples were left indoors and outdoors to investigate migration of salts also called as efflorescence. Concrete mix designs without pigment additive showed higher compressive strength as well as density compering to pigmented concrete. Pigmented concrete outdoor specimens showed increased migration of salts on surface comparing to indoor specimens
