Abstract:
Engineered cementitious composite (ECC), a prominent innovation
in the realm of concrete materials in recent years, contains a
substantial amount of cement in its composition, thereby resulting
in a significant environmental impact. To enhance the environmental
sustainability of ECC, it is plausible to substitute a large
portion of cement in the composition with fly ash, a by-product of
coal-fired power plants. Recent years have seen increased research
in ECC containing high-volume fly ash (HVFA) binder and its
wider application in construction practices. In this particular
context, it becomes imperative to review the role of HVFA binder in
ECC. This review first examines the effects of incorporating HVFA
binder in ECC on the fiber dispersion and fiber-matrix interface
behavior. Additionally, mechanical properties, including compressive
strength, tensile behavior, and cracking behavior under
loading, as well as durability performances of HVFA-based ECC
under various exposure conditions, are explored. Last, this review
summarizes the research needs pertaining to HVFA-based ECC,
proving valuable guidance for future endeavors in this field.
