Among its activities, the construction industry has a significant impact on the environment. In recent years, therefore, emphasis has been placed on the sustainability of building structures and materials, and ways and means are being sought to achieve this. Specifically, it is about reducing emissions and using the waste produced by recycling materials, e.g. aggregate. The motivation for using recycled aggregates is also to reduce dependence on natural resources, which are declining. The article deals with the as...

The structural design of concrete structures needs to result in qualities ensuring structural safety and serviceability, together with durability, robustness, sustainability and resilience. Due to this, the effects of mechanical load, environmental load and even social coherence need to be reflected and included in the formulation of limit states. This is a complex matter involving the time factor, service life, degradation effects, modelling, probability analyses, limit states, costs and other phenomena, and it i...
