ABSTRACT
Abstract Woven fabrics have a great potential in reinforcing thin elements to produce high performance cementitious composites. The weaving process and the interlacing of yarns cause a crimped shape both in fill and warp yarns. The present paper presents a study on the bond between monofilament polyethylene yarns and the cement matrix. The study is performed on curved yarns which were untied from different woven fabrics. The woven fabrics were plain weave with varied yarns density. Straight yarns were also examined for comparison. Pull-out tests were carried out to investigate the bond mechanisms. It was found that the yarns structure geometrical characteristics have a pronounced effect on the bond resistance parameters. The crimped structure is responsible for load cycling while pulling out.
