Temperature cracks are one of the most common quality issues in concrete engineering.
Whether it is large volume concrete (such as bridge piers, high-rise building foundations) or ordinary components (such as floor slabs, walls), cracks may occur due to temperature changes.
These cracks not only affect the appearance of concrete, but also reduce the impermeability and durability of the structure, and in severe cases, even threaten engineering safety.
To effectively prevent and control temperature cracks, it is necessary to first clarify the core mechanism of their occurrence – the stress caused by temperature changes inside the concrete exceeding the material’s own tensile strength.
This article will start from the source of temperature changes in concrete, analyze the process of temperature cracks in stages and types, and reveal the influence of different factors on crack formation.
