Uniaxial Tensile Behavior of Engineered Cementitious Composites (ECC): A Review

Abstract

The high ductility and multiple cracking characters of Engineered Cementitious Composites (ECC) is particular for cementitious materials. In the present paper, recent progress in the uniaxial tensile behavior of ECC is reviewed. Raw materials, mix proportion, tensile specimen size, testing procedure and tensile properties of ECC are summarized according to literature from the last decade. It is conclude that with the addition of ductile fiber, ECC possesses the ability to stretch after the initial elastic stage and due to the bridging effect of decentralized fiber in matrix, crack failure was well controlled which leads to small and tight cracks at the ultimate condition. On the whole, uniaxial tensile strength ranges from 3.2-16.0MPa, ultimate tensile strain from 0.5-8.0%, average crack width controlled below 100ï­m.
