Effect of Short Fibers on the Behavior of Textile Reinforced Concrete under Tensile Loading

摘要

This paper addresses the influence of the addition of short fibers made of alkali-resistant glass on the fracture behavior of textile reinforced concrete (TRC). A series of uniaxial, deformation-controlled tension tests was performed to observe the strength, deformation and fracture behavior of thin, narrow plates made of TRC both with and without the addition of short fibers. Furthermore, multifilament-yarn pullout and single-fiber pullout tests were carried out to gain a better understanding of crack bridging behavior which suppresses crack growth and widening. Various effects of the addition of short fiber on the stress-strain relationship and cracking behavior of TRC were observed and discussed with reference to microscopic investigation of fractured surfaces.
