External sulfate attack is one of the durability problems associated with concrete. Despite a perception that concrete made with recycle concrete aggregate (RCA) is of inferior quality, research has shown that RCA has the potential to satisfy the mec

There are frequent high-temperature geotherm disasters in the tunnels of China's western mountainous regions. The surrounding rock fissure water in the tunnels and underground water contain a great amount of corrosive salt. As a result, the lining co
