From: Flexural behaviour of recycled reinforced concrete beams strengthened/ repaired with CFRP laminates
Steps of applying CFRP laminates on the strengthened beams. a Smoothing and cleaning the surface of the concrete beam. b Free surface after cleaning. c Using toner and cotton to remove any contamination. d Putting the epoxy on the surface of the beams before attaching the CFRPP laminate to it. e Squeeze out the epoxy under the laminate with a solid roller. f The beams were left with the CFRPP laminates that attached for at least 72 h to get full curing
