The Strength Properties of Chemical Attack of Shotcrete using the Aluminate Accelerator

This study investigated the strength of shotcrete with aluminate accelerator to connect with the proper repair methods or monitoring skills in subway, cable tunnel and underground storage. In order to approach these goals, the shotcrete specimens were exposed to acid, sulfate and seawater environments, and strength properties of the shotcrete suffering from the attacking sources were examined.
