| Sumario: | Structural shotcrete can be designed and produced with an improved environmental profile when a performance-based approach (PBA) i$ addressed. The selection of suitable concrete constituents from a broad variety of altenatives can be ruled by the global environmental performance. Not only 1ess energy intensive cement contribute to this objective but the use of locally available aggregates, a better efficiency and increased dumbility contribute as well. This paper is aimed at highlighting a case study where the use of a PBA to structural shotcrete design and characterisation has lead to better homogeneity, increased efficiency while using less energy-intensive cements and almost any type of aggregate. The assessment of the tailored shotcrete is performed through the use of suitable performance indicators, so me of them rather innovative. As a result, it can be stated that it is possible to design and produce a tailored designed structural shotcrete with an improved environmental profile. The application of PBA to the design and characterisation of shotcrete might lead also to a better harmonisation between specification and control stages. |
