2020-6-30  Thermal crack possibly will be a full depth crack. Control of thermal crack width also relies on temperature drop of concrete from the Peak to normal temperature. Avoiding placing of concrete in peak temperature conditions will help reduce thermal cracks. Provision of adequate rebars is also necessary to avoid thermal cracks.

2008-6-5  Surface crack detection by this means is not sufficiently scientific. Therefore, this study proposes to apply short duration (~3ms) pulsed thermography, more specifically named flash thermography (FT), for surface crack detection on concrete structures. The technique has been widely used in the aerospace industry(6),(7) in recent years.

Early Thermal Cracking of Concrete - TII Publications

2021-7-7  3.3 Where a concrete member is restrained, cracking due to early thermal movement is almost inevitable due to the low tensile strength of the immature concrete. In a plain concrete member, if the tensile strength of the concrete is exceeded, one wide crack is induced. This relieves the tension elsewhere and further cracking does not occur. A
