Causes Of Concrete Cracks
Cracks can be caused due to variable conditions existing directly or indirectly in the area of the property, mix design of the structure, improper steel placement and inadequate joint design. There can be also more complex causes for the cracks and damage in the concrete. The in-depth diagnosis of the damage in the concrete structure can be assessed by a concrete professional only, as a person with common knowledge cannot judge the impact in the internal concrete.
Various causes have different concrete repair techniques and so not any concrete cracks shall be repaired through the same technique. There are different types of concrete cracking.
The first type of crack is shrinkage crack. These cracks are easy to spot. They are caused discontinuously and typically appear on the surface of the crack. The width is less than one-sixth of a centimeter, which is less than 2 millimeters. These are caused due to the shrinkage of the concrete in the initial hydration period.
The second type of crack is a structural crack. These are the primary consequence of poor shifting in the soil in the land on which the construction has been done. These are also known as shift cracks or settlement cracks. A structural epoxy is injected in this type of a crack, wherein it acts to prevent further shifting of the soil and causing of cracks, and it does not act as an agent to bond the cracks together, as it may seem to any layman.
The third type of crack is the offset structural crack, in which the concrete repair is not guaranteed. It is a crack, in which, either sides of the crack represent a raised portion. It is also referred to as twisted crack.
