Metals are commonly used in construction, primarily as reinforcement within concrete structures, to enhance strength and durability. The integration of metals, such as steel rebar, into concrete provides the necessary tensile strength that concrete lacks on its own. Beyond structural reinforcement, metals are also used in decorative applications, and as components of advanced cementitious composites. Understanding how metals interact with cement and concrete, particularly under severe environmental conditions like corrosive atmospheres or extreme temperatures, is essential for optimizing the longevity and functionality of concrete structures.
