“…The actual service life of reinforced concrete in real environment is very difficult to predict/ model theoretically, as it depends on not only environmental conditions but also on the heterogeneous nature of cement-based materials. Therefore, it is important to validate the model by imperative long-term field study in a particular environmental condition [105,135].…”

“…1, there are three basic approaches to achieve a sustainable use of concrete: (1) the optimization of the composition of the concrete in view of its environmental impact while maintaining an equal or better performance and lifetime; (2) the improvement of the concretes performance at equal environmental impact and lifetime; (3) the optimization of the lifetime of the building material and the building structures at equal environmental impact and performance. This paper deals primarily with the aforementioned approaches (1) and (2), while the inclusion of approach (3) can be found elsewhere [39].…”

Sustainable structural engineering follows the basic principle that the energy and resources consumption due to the construction and operation of a structure must be minimized. Relating to concrete structures this principle can be realized by the use of the material in the most efficient way considering its strength and durability within the service life of the structure. Againstthis background the presentpaper outlines methods to assess and reduce the environmental impact of concrete and means to increase itsperformance. The presented concept is applied to the concrete type with the greatest potential in sustainability, i.e. green concrete. Thereby, the basic principles of green concrete mix design are introduced and a systematic study of the influence of the cement content on the fresh and hardened concrete properties as well as on durability parameters is presented. From the results it can be seen, that green concretes possess a very high sustainability and, depending on the attack scenario,even might show acceptable durability characteristics whenthey are subjected to corrosive exposures.

“…Generally, the potential of sustainability can be calculated [6] In this equation, "performance" R means (for instance) load-bearing capacity, deformability, resistance to degradation or other properties of the material or structure in corresponding units. The service life L is usually given in years and its definition is described in Section 2.2.…”

Abstract. Efficient sustainability management requires the use of tools which allow material, technological and construction variants to be quantified, measured or compared. These tools can be used as a powerful marketing aid and as support for the transition to "circular economy". Life Cycle Assessment (LCA) procedures are also used, aside from other approaches. LCA is a method that evaluates the life cycle of a structure from the point of view of its impact on the environment. Consideration is given also to energy and raw material costs, as well as to environmental impact throughout the life cycle -e.g. due to emissions. The paper focuses on the quantification of sustainability connected with the use of various types of concrete with regard to their resistance to degradation. Sustainability coefficients are determined using information regarding service life and "eco-costs". The aim is to propose a suitable methodology which can simplify decision-making in the design and choice of concrete mixes from a wider perspective, i.e. not only with regard to load-bearing capacity or durability.
