초록
Shotcrete is NATM technique after tunnel excavation as major tunnel support for ground stability, curtail of execution period and reduction of execution expenses instead of general lining method. It is trend using constantly shotcrete lining. This high-strength shotcrete is require to use as constantly shotcrete lining. This brought out the solution of environmental pollution and harmfulness about human. Accordingly, in this study Specimens of strength measurement was made to develop shotcrete possible to develop in early materials with Cement Mineral Accelerator as NATM method construction. It's compared with existing shotcrete material, Unconfined Compression test, flexural strength test were experimented. The fish poison test was experimented to evaluate an influence of environment. On results of test, Unconfined Compressive Strength and flexural strength was equivalent with 28-day strength of existing material. On results of fish poison evaluation research subject material was founded environmentally friendly for existing shotcrete.
