Evaluation of Mechanical Properties of Hybrid Fibers in Concrete

Abstract

Engineering Cementitious Composites (ECC) is an advanced growing method to increase the longevity of the structure in all behaviour aspects. ECC consist of cement, fine aggregate, fiber and water.High performance, ductility and durability of cementitious matrix can be achieved by addition of fiber. Nowadays, the member of fibers play a vital role to increase the overall structural behaviour of concrete matrix. In that, synthetic-based fibers are used in various applications. So in the proposed work, synthetic-based polyvinyl alcohol (PVA) fiber was used in ECC to evaluate thebehaviour of the structural member. For this study, mortar was casted in a ratio of 1:3 with addition of PVA fiber with different volume fraction such as 1.0%, 1.2%, 1.4%, 1.6%, 1.8%, and 2.0%. The strength characteristic was determined for all the mixes. By obtaining the optimum dosage content from strength characteristics beam and a panel isto be casted to evaluate the structural behaviour properties.
