Micromechanics and Engineered Cementitious Composites (ECC) Design Basis
One of the unique features behind the high ductility of Engineered Cementitious Composites (ECC) is a design basis that is distinctly different from that of high strength concrete. For high strength concrete or members of this family of concrete materials, high compressive strength is reached by particle tight packing. The design basis of ECC, however, is based on synergizing the mechanical interactions between fiber, matrix, and interfaces of the composite so that multiple cracking in tension is attained. This design basis is embodied in a body of knowledge known as the micromechanics of ECC.
