Engineered cementitious composites (ECCs) have been under development at the University of Michigan, Ann Arbor, MI, over the last two decades. In contrast to conventional concrete, ECCs exhibit superior tensile ductility. The average crack width for ECCs is self-maintained to less than about 60 µm (0.002 in.) under imposed strains of up to several percent. The article reviews an experimental study on the alkali-silica reaction (ASR) suppression mechanism of ECCs in light of field experiences.
