One environment that hinders the performance of reinforced concrete is fire. In most cases, this results in the affected part or the entire structure being rendered useless or completely collapsing. When fire mishaps happen in structures, this is the case. This study reviews green structural retrofitting materials for reinforced concrete buildings in an effort to repair damaged structures in an environmentally friendly manner. The information gathered from earlier laboratory test results is assembled to comprehend the impact of room temperature strength properties and varied concrete mix material composition on the residual mechanical properties of concrete. The performance of various fibers, synthetic and natural, as laminate materials for concrete were evaluated, and the study showed that to a significant extent, distressed structural elements could be repaired with retrofits. However, provision of appropriate guidelines for using natural fibre laminates for retrofitting has not been overly explored. This review has highlighted areas that require further study in order to fully understand the residual strength characteristics of concrete exposed to high temperatures, particularly damaged concrete that have been retrofitted with fibers. Overall, the review's findings will be helpful to academics, professionals in the field of civil engineering, and those engaged in construction.

阻碍钢筋混凝土性能的一种环境是火灾。在大多数情况下，这会导致受影响的部分或整个结构变得无用或完全倒塌。当建筑物发生火灾事故时，就是这种情况。本研究回顾了钢筋混凝土建筑的绿色结构改造材料，以期以环保的方式修复受损结构。汇总从早期实验室测试结果收集的信息，以了解室温强度性能和不同混凝土混合材料成分对混凝土剩余机械性能的影响。对各种合成纤维和天然纤维作为混凝土层压材料的性能进行了评估，研究表明，在很大程度上，可以通过改造来修复受损的结构元件。然而，尚未过度探讨如何提供使用天然纤维层压板进行改造的适当指南。本综述强调了需要进一步研究的领域，以便充分了解暴露在高温下的混凝土的残余强度特性，特别是用纤维翻新的受损混凝土。总体而言，该审查的结果将对土木工程领域的学者、专业人士以及从事建筑工作的人员有所帮助。
