Engineered cementitious composites (ECC) are a special type of high-performance fiber-reinforced cementitious composites that is characterized by high-ductility (3–5% strain) and moderate tensile strength (4–6 MPa) with 1.5–2% fiber content by volume. Under tensile deformation, ECC shows strain-hardening behavior and closely spaced microcracks after the first cracking. ECC possesses excellent shear capacity, improved damage tolerance, ability to control crack width, and synergistic interaction with reinforcing bars. ECC has been proposed as a novel alternative for infrastructure materials but to date has not seen wide application in Texas or the rest of the United States. The objective of this project is to identify high priority applications of ECC appropriate to the Texas transportation system.
