Concrete is a quasi-brittle material, and fracture mechanics is essential to comprehending how it cracks and fails. An outline of the development of fracture mechanics principles as they relate to concrete structures is provided in this review. It is addressed how traditional strength-based methods fall short in capturing size effects and post-peak behavior. The importance of nonlinear and energy-based fracture models is emphasized. Examined is the fracture process zone's function in controlling crack initiation and propagation. Important theoretical developments are covered, such as the size impact law and fake crack models. A summary of experimental methods for figuring out fracture parameters like fracture energy is provided. The benefits of standardized testing techniques for accurate data interpretation are examined. The latest advancements in sophisticated measurement methods and numerical modeling are described. The research highlights how crucial fracture mechanics is to enhancing the longevity and design dependability of contemporary concrete buildings.
