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...
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 کاملFiber-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...
متن کاملHygral Behavior of Engineered Cementitious Composites (ECC)
In this paper, the sorption isotherm and the hygral deformation of a tensile strain-hardening fiber reinforced engineered cementitious composite (ECC) is described using a physical model. The influence of using a low alkali content Portland cement on the physical mechanisms of drying shrinkage is discussed. From a durability point of view the crack width of a material as a result of restrained ...
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...
