Abstract:
When concrete is exposed architecturally, as well as being used structurally, the designer must consider a number of factors: structural aspects, properties and characteristics of the material, and construction methods. Apart from the obvious need to consider volumetric effects in design, such as shrinkage, creep, and volume change due to temperature, the very nature of the material requires special study. It is not sufficient to accept "average values" as design criteria, but testing on the actual concrete mix must be performed. Detailing and construction are important considerations for an architectural concrete structure, particularly the proper placement of joints, proper placement of reinforcement, and the method of curing.
