摘要：

This study examined the effect of aggregate size and density on the shear and tensile bond characteristics of the coarse sand coated interface between stay-in-place fibre-reinforced polymer (FRP) formwork and concrete. Shear and tension tests were performed for five test variables according to aggregate size and density. Based on the test results, the appropriate size and distribution density of the aggregates is examined. In addition, based on the shear test results, the local shear bond stress-slip model for each of the test variables was derived through an optimization process.
