(57) The present invention relates to a cement material structure used in the construction field and capable of changing colour by electrochromism, and to the method for producing same. More specifically, the present invention consists of an electrochromic cement material structure containing at least one electrochromic device (7) formed in at least one cavity (1), which is in turn formed in the surface of the cement material structure, the at least one electrochromic device (7) containing a first electrochromic element (2) and an electroconducting electroactive element (8) which are mutually isolated by an electrolyte (3), the structure according to the present invention additionally containing means for applying a differential voltage (4) between the first electrochromic element (2) and the electroactive element (8). The present invention also relates to the method for producing said electrochromic structure.
