N2 - A new cement-based composite material, High-Strength, High-Ductility Concrete (HSHDC), has been recently developed which overcomes the brittle limitations of most concretes and cementitious materials. The material exhibits very high compressive strength relative to other types of concrete, with values exceeding 160 MPa compared with 20-40 MPa for standard concretes. The main advantage of HSHDC is the capability for elongation and strain hardening in tension, with tensile strain capacity nearing 3.5%. HSHDC, developed through a collaborative research effort between the University of Michigan and the U.S. Army Engineer Research and Development Center, provides unique material properties with broad implications for high deflection, cyclic, and impact loadings. An overview of the micro-mechanics-based design principles and formulations of the new materials is presented. Material characterization included measurements of unconfined compressive strength, indirect tensile strength, and hardness. Results from these physical tests, along with microscopic images of the tested material, are reported and discussed.
