Abstract
PVA-ECC is a high performance fiber reinforced cementitious composite that has superior tensile ductility. Due to the absence of coarse aggregate, however, it was found that cracks in PVA-ECC are susceptible to shear. The possible use of coarse aggregate had been demonstrated to increase the resistance of the cracks to shear. In this research, shear beam tests which represented multi-directional stress field were demonstrated to investigate the behavior of PVA-ECC which contained coarse aggregate under static and fatigue loading. From the experiments, a comparable or slight increase in static shear capacity can be expected at structural member level, with a possible of significant fatigue life extension. Furthermore, effective role of aggregate can be investigated from measurement of opening and sliding behavior of main crack.[This abstract is not included in the PDF]
