Korea shotcrete technology has been developed by constructing underground space, roads and rails for expanding Social Overhead Capital. To late, importance of shotcrete is raised due to the efforts for semi-permanent use of underground structure and a long term safety. Shotcrete testing method and quality criterion have been developed continusously in abroad, but there are no standard and quality criterion of shotcrete in Korea. International quality criterion has been used to domestic conditions, so various problems are occurred in construction field, material, mixture, equipment, and so on. In this study, to establish standard of domestic shotcrete, both criteria and quality of shotcrete were investigated and opinion poll was performed in the construction field. Indoor and field test were performed to investigate appliance possibility of high-performance shotcrete.
