Review on the mechanism and mitigation of cracks in concrete

Abstract

Cracks and cavities belong to two basic forms of damage to the concrete structure, which may reduce the load-bearing capacity and tightness of the structure and lead to failures and catastrophes in construction structures. One of the most prevalent faults in concrete constructions is cracking, which, if left unchecked, can greatly diminish the longevity of the building. For the past few years, scientists have worked to understand the complex mechanics behind concrete cracking. It has been found that the primary initiators of plastic cracking include surface finishing, capillary action, bleeding, evaporation, and settlement of solid particles. A number of techniques and measurements have been developed to measure the influence of the various processes that result in concrete shrinkage and cracking. Cracking due to shrinkage and plastic segregation are now also referred to as plastic cracking. Numerous cracking prevention techniques have been suggested, such as fogging, using fewer particles, and using fibres. This cutting-edge study updates the significant growth of research on the subject to what is currently considered cutting-edge and state-of-the-art.
