We all want a home that is both technically sound and appealing, but this isn't always achievable. Natural disasters, soil collapse, construction defects, poor design, and inadequate joints are all factors that lead to the formation of structural cracks. Although concrete fractures can't be totally prevented, they can be handled with the right materials, construction techniques, and design requirements. It's vital to spot such cracks as soon as possible and take precautions. Active cracks are a major problem that needs to be addressed right away since they are structurally unsafe. As a result, it is critical to comprehend the many sorts of fractures, their patterns, and their causes Based. Key Words: Crack Detection Techniques, Repair of Crack, Causes of Crack and Preventive Measures. 1. INTRODUCTION
1.1 Understanding The Crack
Cracking or crushing separates concrete into two or more parts, either completely or partially. Concrete cracking is a unique function that can't be totally avoided, but can be managed and minimized. Concrete, a material with a low tensile strength, is quickly damaged when a tensile stress is given to the structure that exceeds the tensile strength of concrete..
Cracks can be classified into two type categories. a] Structural cracks : Structural cracks can occur for a variety of reasons, such as poor design, congestion of structural members, overloading the ground on which a building is built, or other similar factors. Structural cracks can impair the constancy of a building and make it difficult to repair. Extensive cracks in foundation walls, beams, columns, or slabs are examples of structural cracks[50].
Building cracks are a worldwide issue. The component will crack if the stress applied on it exceeds its strength. External forces such as dead, live, wind, seismic loads, and foundation subsidence can all generate component stress. Temperature swings, humidity changes, and chemical factors can also induce it inside.. Engineers must have a thorough understanding of all aspects of concrete technology. That is, it is about the behavior of building materials, construction technology, and the different sorts of fractures that might arise, their causes, and how to fix them. Cracking, in other words, entails detection, diagnosis, and repair. Subsidence, temperature, shrinkage, and poor construction practices can all cause cracks. We shall describe the many causes of the aforesaid cracks in this project. © 2022, IRJET
