Using the geometrical definition, the second step was to develop a damage mapping of the three structures that form the IX Fort Monument (Fallen, Rebellion and Victory). This will be essential for identifying possible spots where to apply the products in a future stage but also to understand which are the problems that the structures are facing and design the sampling campaign not only to define the concrete properties but also to clarify doubts on the active decay processes.
Once the damage mapping was completed, INES team conducted a set of destructive and non-destructive tests to finalize defining the material properties and condition. Regarding destructive samples, two different samples were obtained from each of the three structures. One of the samples was oriented to determine the concrete compressive strength, its density and porosity as well as the size and shape of the arid and the water-cement content; which required a minimum size to fulfill the laboratory tests standards. The other sample taken was much smaller as the purpose is to conduct a thin sheet test to obtain a microscopic view of the concrete composition.
