Abstract
Concrete can be cracked or crushed into two or more portions, either entirely or partially. It is impossible to completely prevent concrete cracking, perhaps managed and mitigated. When a structure is subjected to a tensile stress that is exceeding the tensile strength of concrete, concrete, a material with a low tensile strength, is swiftly damaged. Building fractures are a global problem. If the component is held under more stress than it can handle, it will crack. Cracks are classified into two types structural cracks and non-structural cracks. Structural cracks endanger safety of building, while non-structural cracks disturb the aesthetic appearance of building. To analyze these cracks non-destructive tests like rebound hammer test and ultrasonic pulse velocity tests are conducted on the structure in this work. Also, various repair methods are studied depending on the nature of cracks. Suitable method that is routing and sealing is implemented for repair of cracks. Cost comparison is done between repair and rehabilitation and demolition and construction of new structure.
