Resumen
Shotcrete is one of the most significant innovations in the construction industry. What began as an experimental technique has evolved into essential technology, valued for its versatility and efficiency in projects ranging from structural repair and stabilization to the construction of tunnels, mines, open-pit excavation linings, and dams. Its ability to be sprayed at high speed onto various surfaces—even under complex conditions—combined with its rapid hardening process sets it apart from conventional concrete placement methods.
The history of shotcrete is defined by key milestones in its development, from the introduction of dry application techniques to the later innovation of the wet process, which greatly enhanced the material’s quality, consistency, and efficiency. These advancements have been accompanied by progress in materials science and technology, optimizing shotcrete’s mechanical properties and durability. Additionally, continuous improvements in application equipment have transformed it from rudimentary manual systems to high-precision automated technologies.
This historical overview not only highlights the technical evolution of shotcrete but also underscores its impact on modern construction methodologies. This review explores the most significant moments in its development, along with the progressive and incremental innovations that have solidified its status as a fundamental tool in engineering projects and the construction of complex infrastructure worldwide.
