Performance of Partially Bonded Engineered Cementitious Composites (ECC) In Concrete Block Masonry

Abstract

The objective of this study is to examine the behavior and determine the potential implications of Engineered Cementitious Composites (ECC) to strengthen the concrete block masonry by using a unique method of partially bonding the tension face as tension strengthened beam under the out of plane loadings. The specimens under investigation were comprised of two categories i.e. un-strengthened concrete block masonry beams and tension strengthen beams with different thicknesses of ECC layers. All the specimens were experimented under the four point loadings to evaluate the flexural performance of fabricated beams. The current study reveals that the partially bonded ECC strengthening of concrete block masonry beams has significantly improved the strength and deformability.
