Abstract
Concrete structures and built infrastructure are essential for modern civilization due to the increasing urbanization, population growth, and corresponding infrastructure needs. However, extreme weather and prolonged exposure to humidity can lead to the irreversible degradation of various materials used in built infrastructure, primarily due to water penetration and freeze–thaw cycles. This review examines the effectiveness and successful application of protective surface coatings on concrete, a major construction material. Superhydrophobic coatings meet the demands of various applications, offering anti-microbial resistance, corrosion resistance, contamination prevention, water repellence, drag reduction, anti-icing, anti-fogging, anti-adhesion features, and self-cleaning capabilities. Nanocomposites are known for their improved mechanical, thermomechanical, and thermal properties…
