The cracks that are associated with the expansion of concrete are known as expansion concrete cracks.

✔ These are the type of cracks that are formed as a result of the expansion of concrete, particularly in hot climatic conditions.

✔ Due to the extreme heat, the concrete begins to expand and it pushes away anything present on its way such as a brick. Since neither of them can flex, the resulting expanding force is so strong that it can cause cracking of the concrete.
