Vinoth Kumar M.E. Structural Engineering, Kumaraguru College of Technology, Coimbatore, Tamilnadu, India G. Karthikeyan Assistant Professor, Department of Civil Engineering, Kumaraguru College of Technology, Coimbatore, Tamilnadu, India ABSTRACT Engineered Cementitious Composite (ECC) is an ultra-ductile cement-based material reinforced with fibers. It is characterized by high tensile ductility and tight crack width control. ECC is emerging in broad applications to enhance the loading capacity and the durability of structures. However, ECC also faces a limitation on dimensional stability and on economical and sustainable issues. The micromechanics concepts, which support the development of ECC, are also briefly presented. Results of the beam test indicate that brittle failures as shear failure and bond splitting failure observed in the RC beams can be prevented by using PVA-ECC in place of the concrete. As a result, the beams with PVA-ECC indicate excellent ductile manner. The result is a moderately low fiber volume fraction (<2%) composite which shows extensive strain-hardening.
