Marine concrete refers to the specialized concrete formulations used in marine environments, where structures are subjected to aggressive conditions such as saltwater immersion, tidal fluctuations, and biological degradation. This type of concrete is designed to withstand the harsh chemical, physical, and biological factors that are prevalent in such settings. The durability and longevity of marine concrete are paramount, considering the critical nature of the infrastructure it supports, such as piers, breakwaters, and sea walls.
