This article presents a comparative analysis of various studies focused on concrete performance at high temperatures, particularly considering the degradation and possible recovery of its structural capacity after a fire. Studies are examined that address variables such as the type of concrete used, the incorporation of metallic or synthetic fibers, the addition of pozzolanic materials, the cooling methods applied, and post-fire diagnostic techniques. The reviewed findings indicate that the use of steel or glass fibers can contribute to improving the thermal stability of concrete, although their effectiveness depends on the type of mix and the thermal conditions achieved. Similarly, the incorporation of fly ash has shown positive effects on the residual strength of self-compacting concrete. Both experimental approaches and theoretical models are included, allowing for the assessment of t...
