Early examples of this type of adorn
28、ment are the streets and paving throughout the city of Pompeii near Naples, Italy. Early deco-rative concrete used colored aggregates and varying shapes or natural materials embedded in concrete paving.Traditionally, concrete has been specified more for its functional characteristics than as an enha
29、ncement to the aesthetics of the structure. Landscape architects were leaders in using concrete flatwork to enhance the visual appeal of hardscapes. Using color and texture introduced concrete as a landscape feature in addition to its functionality. An example is flatwork textured and colored to rep
30、licate the look of slate, brick, or natural stone as shown in Fig. 1.1a and 1.1b.The use of decorative concrete has been well received and considered as an alternative to other building materials for durable, versatile, and economical finishes. More designers are creating greater aesthetic appeal in
31、 projects by using one or more combinations of special concrete placement techniques including integral concrete colors, color hard-eners, chemical stains, pigments and dyes, surface texturing, jointing, exposed aggregate, surface embossing, polishing, Fig. 1.1aStamped, colored concrete with slate a

The combinations of techniques and mediums described in this guide are exclu-sive; they cannot be replicated by any other durable medium.1.2ScopeThis guide describes several techniques for imparting aesthetic finishes to concrete, many of which can be combined
34、 for unique effects (Fig. 1.2). The guide provides detailed practical guidance for achieving aesthetic effects using proven techniques, both within and beyond the context of ACI 302.1R, which also governs these concrete elements.Recommendations for the production of cast-in-place decorative concrete
35、, stains, and overlays are presented. In addition to attention to specified materials, mixture designs, concrete placement, curing, protection, sealing, and other treatments, consideration of the effects of these treatments on the overall aesthetics of the structure is also addressed.CHAPTER 2DEFINI
