The article analyzes possibilities of using additive manufacturing in the building industry, especially in the field of reconstruction of building structures. On concrete examples, growing potential and future perspective of the additive manufacturing technology are demonstrated in the text. There are also presented cases of reconstructions, especially in combination with the 3D scanning method. At other points, the basic principles of this technology are presented, its advantages over conventional technological procedures and the possibility of application of special concrete as a primary material in the context of 3D printing and the construction industry.

The paper analyzes the issue of the absence of technical standards and regulations for exposed concrete in relation to its aesthetic quality and defines the possibilities of approach to the design and project documentation that would effectively lead to the desired visual result. Achieving a high-quality exposed concrete area is only possible if all the mentioned phases of the process are adhered to and the standards related to the execution of concrete structures are respected.

Colored concrete is widely used in contemporary architecture due to its aesthetic potential. Adding a color pigment to the concrete mix opens up for architects other possibilities for work with concrete. They are no longer limited by its natural gray color. Choosing the right type of pigment is essential for quality and long-term satisfaction with the final work, while it is necessary to be aware of certain limits resulting from the natural behavior and nature of concrete. The article characterizes an overview of pigments suitable for coloring concrete mixtures and demonstrates the change in color saturation after exposure to weathering over time. The measurement was performed on experimental concrete samples stained with yellow, red and green pigments
