The most common concrete deterioration processes in bridges

摘要

Typically, concrete elements such as concrete decks, pier caps, piers and beams near joints that are exposed to weather, moisture and aggressive chemicals are more susceptible to degradation. The most common manifestations of concrete deterioration are cracks, spalls, delamination and efflorescence. Cracks Structural deficiencies are one of the causes of concrete cracks, which are mostly due to improper design and detailing of concrete structures. Structural cracks caused by such deficiencies are usually encountered in highly stressed areas where demand stresses are greater than the resistance of reinforced concrete.
