Repair of Cracks on Concrete Structures

Abstract

Cracks in concrete structures have many causes. They can affect the appearance or indicate significant structural loads or lack of durability. Cracks can represent the full extent of the damage or indicate serious problems. Its importance depends on the type of structure and the type of cracking. For example, cracks that are acceptable for buildings may not be acceptable for water retention structures. Correct crack repair depends on knowledge of the causes and selection of repair procedures that take these causes into account. Otherwise, the repair can only be temporary. Cracks are a typical defect that are unavoidable in concrete. If cracks exceed the allowable widths defined in the codes of practice, they considerably reduce the strength, stiffness and durability of the concrete structure and therefore need to be repaired. However, many components are often needed, such as reinforced concrete structures need repair to restore structural integrity and protect the reinforcement Weather conditions. Different types of materials and methods are available. Repair of protruding cracks in concrete structures. In this paper, causes of cracks, repair materials and the repair method are been discussed. Successful long-term repair procedures must attack the causes of the cracks as well as the cracks themselves.

“…It can also cause economic disruptions due to traffic congestion and rerouting associated with the concrete cracks repair works [7]. In Europe, maintenance and repairs for old structures are estimated to account for around 50% of the total construction expenditures, wherein $50 billion were expended for damaged bridges and viaduct repair works [8]. The Philippines also expended a total of Php 6.3 Billion for the alteration and repairs of existing structures in 2019, a massive increase of 21.7 % compared to 2017 [9].…”
