Cover Story: Concrete is the most consumed material on earth, second only to water. Protection strategies against ingress of water and other species causing corrosion and deterioration are of utmost importance, today more than ever. We exploit our expertise in wettability to investigate the hydrophobic performances of a huge variety of concrete surface treatments found in the literature and categorized, according to the European standard, by coating, pore blockage and impregnation. Beyond wettability, are they effective against reinforcement corrosion? Can they also exert an icephobic action? To what extent can they be environmentally sustainable? These and other points are brought into focus here. View this paper
