The subject of this final work is the design of architectural concrete, i.e. concrete that will be permanently exposed to views and therefore requires special care in the selection of concrete materials, design, installation and finishing to obtain the desired architectural appearance. Today, visible concrete surfaces are in high demand both as a stylistic tool and as a form of expression of modern architecture. Namely, large areas of concrete in buildings can contribute to aesthetics only if they are made with a minimum amount of defects and irregularities that are usually present. Concepts of concrete are explained with an emphasis on architectural concrete and its importance when designing and building unique buildings in which architectural concrete was used. Architectural considerations for acceptable concrete surfaces, design criteria for acceptable results, and architectural design details are then presented, as well as structural considerations for what designers and contractors must keep in mind in order to produce a structure capable of withstanding loads and stresses without excessive cracking or deformation that could reduce the architectural appearance of the structure. The topic of formwork is presented in detail, with divisions into groups, the choice of materials and the methods of designing, making and maintaining formwork in the use of architectural concrete. The entire technology of concreting is described, with an emphasis on the composition of architectural concrete, methods of installation and formwork, and the influence of such a construction method on the aesthetics of buildings. Finally, the result of such performance in the execution of this type of concrete elements is shown on several examples of best practice in the USA, where imposing buildings in which architectural concrete was used are shown with pictorial attachments.
