The article discusses the terms and definitions that are increasingly appearing in the open press and on the Internet, confusing well-established concepts. The purpose of considering terminology issues is an attempt to draw the attention of the community of builders – scientists and practitioners to the inadmissibility of inaccuracy and incorrect choice of terms and definitions in the technical, scientific and even regulatory literature.
The article discusses the transformation (changes) of terminology in the field of dense concretes, reinforced concrete structures, as well as structures based on a building composite – steel fiber reinforced concrete. In particular, concrete is a composite, reinforced concrete is not a collective name for reinforced concrete structures and products, but material, moreover, is composite. At the same time, steel fiber concrete is a hardened concrete. This approach is an important reason for restraining widespread use in the practice of building structures based on steel fiber reinforced concrete.
These terms are often used in the open press, depriving the discussed topics of physical meaning, and, as a result, the impossibility of obtaining the expected result.
At the same time, the open press provides information on composite materials, the peculiarities of creating and managing their properties. The article presents the established generally accepted terms and definitions that correspond to the physical nature of concrete, reinforced concrete structures, composite materials and structures based on composite – steel fiber reinforced concrete. The definition of composite materials, the principles of their creation, as well as the features of the composite – steel fiber reinforced concrete and methods of forming its structure are presented. A method is shown for obtaining the properties of steel fiber reinforced concrete in accordance with the stress-strain state of the developed structural element and creating structures based on it with properties specified in accordance with the conditions of their operation and having technical and economic indicators that exceed those of standard structures – analogues.
