To improve the economic benefits of engineered cementitious composite (ECC) and control the repair cycle, the polypropylene fiber-sulfoaluminate cement-based (PP-SACC) repair materials were designed with polypropylene fiber featuring low cost and sulfoaluminate cement featuring fast hardening and early strength employed as the key components. The influence of water-binder ratio, fiber content, and aggregate size on the bending properties of the repair materials was explored. In addition, the grey relation model was used to comprehensively evaluate PP-SACC under all working conditions. The results indicate that the fiber content is the most important factor that affects the strength, toughness, and crack characteristics. The influence factors of fiber content on initial crack strength, toughness index, and average crack width are −0.68, 0.79, and −0.98, respectively. The aggregate size can significantly affect the crack characteristics. The influence factor of quartz sand size on the average crack width is −0.86. The water-binder ratio also greatly affects the strength and toughness, and a reasonable water-binder ratio is beneficial to leverage the bridging effect of the fiber. The PP-SACC repair material has excellent toughness and flexural hardening properties.
