Monotonic and fatigue performance in bending of fiber-reinforced engineered cementitious composite in overlay system

This paper presents an experimental study and theoretical analyses on the monotonic and fatigue performance in bending of a polyvinyl alcohol (PVA) fiber-reinforced engineered cementitious composite (ECC) overlay system. The influence of the interfacial characteristics between overlay and old concrete substrate on the overall bending performance is investigated. The experimental results show th...

Design of Engineered Cementitious Composite Suitable for Wet - Mixture Shotcreting

An engineered cementitious composite (ECC) suitable for wet-mixture shotcreting (sprayable ECC) in the fresh state, while maintaining tensile strain-hardening behavior in the hardened state, has been developed by employing a parallel control of micro-mechanics-and rheology-based design. In the development concept of sprayable ECC, micromechanics is adopted to properly select the matrix, fiber, ...

Rheology, fiber dispersion, and robust properties of Engineered Cementitious Composites

The capability of processing robust Engineered Cementitious Composites (ECC) materials with consistent mechanical properties is crucial for gaining acceptance of this new construction material in various structural applications. ECC’s tensile strainhardening behavior and magnitude of tensile strain capacity are closely associated with fiber dispersion uniformity, which determines the fiber brid...

Fiber-Bridging Constitutive Law of Engineered Cementitious Composites

This paper is on modeling and measuring fiber-bridging constitutive law of Engineered Cementitious Composites (ECC), a high performance fiber-reinforced cementitious composite featuring high tensile ductility. Fiber-bridging constitutive law plays an important role in the multiple cracking behavior of ECC. Therefore, proper control of fiberbridging behavior through tailoring material microstruc...
