Causes, Prevention and Repair of Crack in Building a Review

Crack construction is the most common type of problem in any type of building. So, it is important to understand the cause and the measures to be taken for prevention. Some erroneous steps during construction and the inevitable reasons for different types of cracks begin to appear in different parts of the building and non-building. Therefore, timely identification of such cracks and preventive measures is essential. Though cracks in concrete cannot be prevented entirely but they can be controlled by using adequate material and technique of construction and considering design criteria. Structural cracks are the one whose inherent cause lies in either in incorrect design, or faulty construction or overloading and are the one which can endanger the safety of a given structure. On the other hand, the non-structural cracks are the one which have the underlying origin due to moisture or thermal fluctuations, elastic deformation, creep, chemical reaction, or reason related to the foundation soil such as it movement or settlement or unhindered vegetation. Non-structural cracks are usually caused by stress caused inside the building materials and this usually does not directly cause structural deterioration. In this paper, we will discuss the types of cracks, the causes of cracks and the precautionary measures to be taken and the strategies for treating cracks.
