In this paper, a research study is presented focusing on the effect of substituting brittle concrete in conventional reinforced concrete column members with a ductile engineered cementitious composite (ECC). Based on the material properties of ECC, the interaction with structural reinforcement is characterized by compatible deformations of the reinforcement and ECC matrix in the elastic and ine...

Abstract: The Quasi-static mechanical properties of hybrid fiber (steel fiber and Polyvinyl alcohol (PVA) fiber) reinforced cementitious composites (HFRCC(SP)) were investigated by compressive and tensile experiments. The compressive strength, peak strain, elastic modulus and tensile strength are studied as compared with that of engineered cementitious composite (ECC). Study results indicate th...

This paper discusses the use of fracture mechanics for the microstructure tailoring of a fiber reinforced Engineered Cementitious Composite (ECC) to achieve extreme tensile ductility at the composite scale. It demonstrates that fracture mechanics applied to control fracture phenomena at the micro and meso material scales can lead to suppression of fracture failure at the macro structural scale....

Cement-based composite materials like Engineered Cementitious Composites (ECCs) are applicable in the strengthening of structures because of the high tensile strength and strain. Proper mix proportion, which has the best mechanical properties, is so essential in ECC design material to use in structural components. In this paper, after finding the best mix proportion based on uniaxial tensile st...

Synopsis: This article reviews the recent advances in the research of Engineered Cementitious Composites (ECC), a class of microstructurally tailored fiber reinforced cementitious composites. The design basis, the processing routes, and some ECC performance characteristics in structural applications are highlighted. This article is dedicated to Professor Surendra Shah, in honor of his seminal c...

The influence of different cooling regimes (quenching in water and cooling in air) on the residual mechanical properties of engineered cementitious composite (ECC) subjected to high temperature up to 800°C was discussed in this paper. The ECC specimens are exposed to 100, 200, 400, 600, and 800°C with the unheated specimens for reference. Different cooling regimens had a significant influence o...
