Comprehensive strategy for HSC best performance in extensive applications of landmark works in Italy

The paper points out the significance of Limestone concrete, as high performance concrete applications, starting from the following key construction requirements: in large public works with characteristic very high durability, the choice of a technical solution it is not at all dependent on the construction cost only. In fact in this work, life service and safety performances, that slightly increase the construction cost, are of paramount importace. Starting from this assumption, new materials, in particular new concretes, may be able to notably cut life service and safety cost, considerably improving the performance cost ratio of the selected solution, due to the large cut of maintenance cost. In particular the paper referres to a compreensive campaign of tests shared among different universities and private laboratories in Italy, which aims to grow Guide Lines for different uses of Limestone concrete, as HPC, in different structures typologies and environmental conditions.
