ABSTRACT
Results of a preliminary study examining the potential of steel fibre reinforced grout as a method of masonry wall reinforcement are presented, along with a brief literature review outlining past applications of steel and other fibres to masonry walls. Various fibre lengths including 13 mm straight, 30 mm hooked and 60 mm hooked are used in the grout mixes, with the aim to produce a self-consolidating grout that could be cast into the cores of concrete block walls for in-plane strengthening. Grout tensile strength is evaluated from flexural tensile tests performed on 150 x 150 x 450 mm beams according to ASTM C1609. Compressive properties are determined through direct, uniaxial compression tests performed on 100 mm diameter cylinders. Slump flow test results are also reported.
