Investigation on Crack Recovery Behavior of Engineered Cementitious Composite (ECC) Incorporated Memory Alloy Fiber at Low Temperature

Hygral 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 ...

Shape recovery of shape memory alloy fiber embedded resin matrix smart composite after crack repair.

Ni-Ti shape memory alloy fiber embedded resin matrix composites were produced for evaluation of "smart denture", a newly developing denture with the function to close its own crack. Their bending strength and shape recovery after instant crack repair was estimated. The embedded fibers did not decrease the bending strength of the composite after repair. The crack closure of the composites was pe...

Headed Anchor/Engineered Cementitious Composites (ECC) Pullout Behavior

In this paper, the inelastic damage process in Engineered Cementitious Composites (ECC) in the high stress concentration zone adjacent to the head of an embedded anchor under tensile load was examined experimentally and numerically. An FEM model together with a tensile strain-hardening material model of ECC was developed to simulate the damage process leading to final failure. Experimental obse...

Fatigue Response of Bridge Deck Link Slabs Designed with Ductile Engineered Cementitious Composite (ECC)

Link slabs designed for macroscopically crack free concrete bridge decks system were experimentally tested. The property requirements of the link slab material were considered. Special focus was placed on the fatigue and durability performance. Introduction of a ductile Engineered Cementitious Composite (ECC) material is proposed for its ability to control crack width and to exhibit high ductil...
