Interaction between Steel Reinforcement and Engineered Cementitious Composites
Engineered Cementitious Composite (ECC) is a special type of HPFRCC designed using micromechanics concepts which take into account the mechanical interactions between fiber, matrix and interface in deformation processes under load. While the properties of ECC have been extensively investigated, the interaction between ECC and steel reinforcement has not been studied. This interaction is importa...
متن کاملDesign of green engineered cementitious composites for pavement overlay applications
The construction, repair and rehabilitation of concrete pavements relies on the production and flow of large quantities of concrete and its constituents. Within the US, nearly 43 megatons of cement are used annually for the construction, repair and rehabilitation of concrete pavements, accounting for over 39 megatons of CO2 emissions. To reduce environmental impact and improve the sustainabilit...
متن کاملDurable Overlay Systems with Engineered Cementitious Composites (ECC)
This paper reviews recent research on the application of an engineered cementitious composite (ECC) as overlay in the repair of deteriorated concrete structures. ECC is an ultra-ductile fiber reinforced cement based composite, that has metal-like features when loaded in tension. The uniaxial tensile stress-strain curve shows a ‘yield’ point, followed by strain-hardening up to several percent st...
متن کاملEngineered Cementitious Composites
This paper overviews Engineered Cementitious Composites (ECC) as an emerging construction material. Emphasis is placed on the accumulated knowledge on durability, safety, and sustainability of reinforced ECC (R/ECC) structures, recognizing that the concrete of the future must meet these characteristics. In light of recent and future full-scale field applications of ECC, the limited studies on l...
متن کاملGeneral Design Assumptions for Engineered Cementitious Composites
The use of Engineered Cementitious Composites (ECC) for structural design requires a number of assumptions of the material, some of which can be drastically different from those suitable for normal concrete and tension-softening fiber reinforced concrete. This contribution focuses on design assumptions of the constitutive models of ECC in tension and compression. Specifically, while the tensile...
