Case Study 

Bending reinforcement of concrete wall using S&P slot-applied laminates (FRP 2014_04)

Solution 

With the dismantling of the cladding, it was necessary to reinforce the 3.8-meter-high outer wall against additional bending moment at the middle of the wall. According to static calculations, an application of 3 m long S&P CFK-Laminates 150/2000 (dimensions 20 x 1.4 mm) in pairs, spaced 50 cm apart, was necessary. To avoid additional UV protection coats and work, the laminates were inserted into ca. 8-mm-wide milled slots. The load-transferring application of the laminates is ensured using S&P Resin 220, 2-K epoxy adhesive, which is applied on a prepared bearing substrate in an unloaded state (empty tanks).
