Research and Development of Shotcrete

In recent decades, shotcrete technology has developed rapidly in civil engineering. A lot of practice at home and abroad has proved that shotcrete has shown its unique functions and obvious benefits in the engineering fields such as supporting lining of mine roadway and underground engineering, reinforcing and reinforcing of building structure, stabilizing of rock and soil slope, building of thin wall structure with complex shape and water transmission and filling structure. It can be expected that with the continuous development of transportation, energy and material industry, a large number of urban underground engineering and complex public buildings are constructed, and the increasing number of building structure reinforcement projects, the application field of shotcrete will be increasingly broad. This paper mainly introduces the research progress, construction technology and future development direction of shotcrete in recent decades.
