Influence of BFRP Mesh on UHPC Wet Bonding Performance

As an effective method of strengthening concrete in the marine environment, wet bonding has maintained efficient application mode for many years. At present, research on behavior UHPC is very rare, so order to investigate interfacial performance between basalt fiber-reinforced plastic (BFRP) mesh cloth and ultra-high (UHPC) under conditions, forty-eight BFRP-UHPC specimens were carried out influence dry/wet type, depth, thickness BFRP UHPC, failure mechanism interface was revealed by SEM detection. The test results show that better than dry process. With increasing mesh, stress shows opposite trend, respectively. fiber interlayer structure weak link BFRP; with increase normal decreases gradually. When depth wet-bonded 5 mm, reinforcement effect best, maximum 74%, tensile strength ratio as high 1.74. Compared traditional FRP reinforced construction without can greatly improve performance, which provide a theoretical experimental basis design bonded engineering. Due form distribution direction steel fiber, mechanical occluding will be generated at these two factors are valuable this field, related work needs further proceed.
