Deterioration is the gradual weakening, damage, or reduction in the strength and durability of a building or construction material due to age, weather, chemical action, poor maintenance, overloading, or environmental effects. It affects the appearance, safety, and service life of a structure. Common signs of deterioration in concrete and masonry structures include cracking, scaling, spalling, and delamination.
