In this study, a fast-drying ultra-high strength grout material was developed. The physical properties, fatigue performance, and failure mechanism of the newly developed grout material were clarified through quality inspections and uniaxial cyclic compression tests of several prepared specimens. Uniaxial compressive loading tests were conducted on small-scale models with and without shear keys in order to assess the structural performance of the newly developed grout material. The newly developed grout material and an existing high-performance grout material were compared, and the test results showed that the newly developed grout material had outstanding advantages with regard to the setting time, fatigue performance, and structural performance compared to the latter.
