by For a long time, due to a lack of sufficient understanding of the durability of concrete, builders have only considered strength in design and construction.
In addition, the harsh environment in which highway bridge and culvert structures are located has exposed a large number of problems caused by insufficient durability.
Recent research and engineering experience have shown that considering preventive protective measures during the design phase and strengthening quality control during construction are effective means of improving the durability of concrete structures.
