| Abstract | ||
| In this paper, the structural behavior of reinforced concrete beams made of pumice stone (PS) with aluminum powder (AP) after exposure to fire and rehabilitation by three different techniques (concrete jacket, steel plates and carbon fiber reinforced polymer (CFRP)) was studied. The beams were subjected to fire at 800°C, with a period of 2 h. As a result, the rehabilitation of beams after fire by using the different techniques has a positive effect on loading capacity in bending and deflection for all concrete mixes, but the rehabilitation by concrete jacket is the best technique on the flexural behavior in this study and then comes rehabilitation by steel plates. In addition, the rehabilitation of beams using CFRP strips after fire has a positive effect on flexural behavior regardless concrete type, but need to improvement of glued method | ||
