Architectural concrete is aconstruction material composed of cement, admixtures, sand, stone, chemicaladditives, etc. The architectural characteristic of this type of concrete isprovided by its surface, which presents several aesthetic aspects (such as colourand texture) determined by different finishes. Colour is the consequence of incorporatingpigments in cement. Systems or atlases have been elaborated following diverseprinciples, which include sketching figures and classifying colours accordingto different degrees of lightness, saturation, and hue. This paper proposessuch a systematization of color-surface-finish concepts and specifies theingredients and procedures involved in their respective production. The proposalentails diagrammed images along with summarized information developed as anAtlas of Architectural Concrete. To develop the atlas, two groups of mortarswere elaborated, each group with red, yellow, and black pigments. The colourwas defined by using CIELAB colour space, and their evolution was compared usingCIEDE1976 and CIEDE2000 colour difference formulas. The gloss was also analysed.Results have been represented in six images to allow quantification andvisualization of the differently coloured mortars. An important colourvariation was observed that developed as of day seven up to day twenty-eight. Associatedwith an increasing gloss, the intense formation of calcium carbonate deposits,however, was produced a discouraging result.
