Details of an experimental program comprising of concrete cylinders exposed to different combinations of uniaxial loading, temperature and exposure time, to assess change in its stiffness and strength properties is discussed. Further, an attempt to repair companion thermo-mechanically damaged cylinders using carbon fiber reinforced polymer (CFRP) for mechanical strengthening and geopolymer for thermal insulation before exposing them to combinations of mechanical load and temperature is also presented to assess the efficacy of this system. A Hygro-thermo-chemo mechanical model that has been discussed in the literature is used to obtain strains both in the primary concrete and in the insulated repaired system. Concrete is treated as a deformable, multiphase porous material and so is the geo-polymer repair material. FRP is treated as an elastic brittle material. © 2020 IABSE Congress, Christchurch 2020: Resilient Technologies for Sustainable Infrastructure - Proceedings. All rights reserved.
