Embodiment 1
[0017] Mix epoxy structural glue, quartz sand, and carbon fiber in a ratio of 5:1.5:2 evenly (the length of carbon fiber is 3mm, and the particle size of quartz sand is 2mm), and paint it on a concrete wall several times; the thickness of each brushing is 0.3 -0.4mm, the interval between each painting is 2 hours, and the next painting will be done after drying until the thickness is 2mm. After testing, the tensile strength is 3250Mpa.
Embodiment 2
[0019] Mix epoxy structural adhesive, quartz sand, and carbon fiber in a ratio of 5: 2.5: 4 evenly (the length of carbon fiber is 12mm, and the particle size of quartz sand is 6mm), and paint it on a concrete wall several times; the thickness of each brushing is 0.4 -0.5mm, the interval between each brushing is 2.2 hours, and the next brushing will be done after drying until the thickness is 3mm.
[0020] After testing, the tensile strength is 3415Mpa.
Embodiment 3
[0022] Mix epoxy structural glue, quartz sand and carbon fiber in a ratio of 5:2:3 evenly (the length of carbon fiber is 20mm, and the particle size of quartz sand is 10mm), and paint it on a concrete wall several times; the thickness of each painting is 0.5 -0.6mm, the interval between each painting is 2.5 hours, and the next painting will be done after drying until the thickness is 5mm.
[0023] After testing, the tensile strength is 3625Mpa.
