Crack Repair in Existing Concrete Structures: Progress in Research and Applications

Abstract

Concrete structures, among the most widely used building types, often develop cracks during construction and service due to factors such as construction quality, load effects, and environmental conditions. This review presents a thorough analysis of recent advancements in concrete crack repair, emphasizing the need for effective maintenance strategies in aging infrastructure. This paper integrates advanced laboratory research with real-world engineering applications to assess both conventional and innovative repair materials and methods, offering an overview of widely adopted techniques that provide valuable insights for researchers and practitioners aiming to enhance the durability and longevity of concrete structures.
