ACI 533R-11 (R2021)

The widespread popularity of concrete as a building material can be attributed to the availability, favorable properties, and geographic distribution of its naturally-occurring mineral constituents. Concrete is easily formed and molded, comparatively economical, and durable in its finished state. Architectural precast panel use has increased because of the nature of concrete as a material and the fact that prefabricated components add to construction efficiency. By exposing decorative aggregates, using veneer facing materials, and by varying sizes, shapes, and textures of panels, the engineer/ architect can respond creatively to client needs.
