Surfology Based Concrete Repair Engineering

Research projects performed at the University of Li ege and the Warsaw University of Technology have pointed out the importance of takin g care about surfology of materials: if durability also means sustainability, we may then c o sider that optimization in material selection is essential for repair efficient. Surfol ogy contributes to understand what will make the contact effective or not, and allow interaction s of variable intensities between the materials. Different scales of observation – micro to macro are needed to exactly represent what happens when materials are put into contact.
