The method of execution the installation of strengthened material on building structural elements is sometimes a problem because it requires special expertise and expensive. In addition, structural elements strengthened using mortars or additions concrete have shown a collapse that begins with the release of these strengthening material making it difficult to be composite. This research has been tried alternative strengthened using cold formed steel (CFS) profile that were bonded with Epoxy Sikadur CF-31 and Dynabolt M10 so that the strengthened material becomes composite with the existing slab. The purpose of this slab strengthened was to increase the capacity of reinforced concrete slabs to resist bending loads. Five concrete slab test have been made with dimension 45x145x12 cm with longitudinal reinforcement Ø10-140 mm and transverse reinforcement Ø8-650 mm. The four slabs are strengthened using CFS type C75, 0.75 with spacing of 200 mm. Two slabs use the Sikadur CF-31 Epoxy as glue (SSE) and the other two use Dynabolt M10 as shear connectors (SSD). Furthermore, a flexural test was carried out by given one point load in the middle of spans. The results have shown an increase in the flexural load capacity of SSE and SSD. Moreover, the use of Epoxy Sikadur CF-31 as a glue has increased the stiffness of the strengthened slab while the use of Dynabolt can maximize the ability of CFS to carry bending loads.
