EFFECT OF PVA FIBER RATIO ON MECHANICAL AND DIMENSIONAL STABILITY PROPERTIES OF ENGINEERED CEMENTITIOUS COMPOSITES
Published: 12 Jul 2016
Abstract: Engineered Cementitious Composites-ECC is a type of high-performance fiber reinforced cementitious composites with high ductility and multiple micro-cracks under mechanical loadings. In literature, poly-vinyl-alcohol (PVA) fibers, %2 by volume, are used in the production of ECC. The aim of this study is to determine producibility of ECC with less PVA fiber ratios as %1.75, %1.50, %1.25 and %1.00. Mechanical (compressive and flexural strength) and dimensional stability (drying shrinkage) tests were performed on ECC samples. As a result, ECC can produce with less PVA fiber ratio for specified purposes.
Keywords: ecc, pva fiber, compressive strength, flexural strength, drying shrinkage
