Abstract: Common cement-based materials have weak tensile strength and easy to crack, however, these shortcomings have been overcome by a new type of fiber reinforced cement-based material—engineered cementitious composite (ECC). High ductility, high toughness and high energy dissipation capacity are the distinctive characteristics of ECC, which are attributed to the steady-state cracking process based on the micromechanical design. After the brief introduction of the development background and design mechanism of ECC, this paper reviewed the researches on dynamic mechanical properties and explosion/impact resistance of ECC. Meanwhile, the influences of high strain rate and high temperature on the performance of ECC were analyzed, and the problems that need to be solved in the application of ECC in protection engineering were also pointed out. Finally, suggestions for future researches and developments of ECC were put forward.

Key words: engineered cementitious composite, dynamic mechanical property, strain rate effect, strain hardening, anti-explosion performance, impact resistance performance
