Abstract
The technical (service) lifespan of concrete is a crucial element in the construction sector, where the quality of the concrete mix and execution technology plays a decisive role in the performance throughout the entire functional life of structures. This presentation explores the importance of a well-designed concrete mix and how it contributes to the sustainability (overall environmental impact) and longevity of structures. We will examine the influence of reducing the environmental impact of concrete, resistance to environmental exposure conditions, and maintenance needs of concrete structures. By providing insights into the relationships between mix composition and lifespan performance, we emphasize the necessity of careful material selection and precise execution technology as the foundation for sustainable construction practices. The presentation will offer practical recommendations for improving the technical lifespan and reducing the environmental impact of concrete by focusing on the quality of the concrete mix and execution technology.
