Fine cracks are commonly observed in freshly laid concrete and their appearance is due to the phenomenon of plastic shrinkage. As the name implies, these cracks are very small, about 0.003 inches (0.08 mm) wide, and can be very shallow. The main cause behind the generation of fine cracks in concrete is plastic shrinkage, which is the rapid depletion of moisture from fresh concrete within its plastic state.

Your home's foundations, the concrete walls surrounding a basement or low-rise space, support the full weight of the house, so it's natural to worry if you discover cracks in the concrete. Repairing a fine crack in a concrete structure involves filling the space with a material that adheres well to the concrete, restores its original appearance, and prevents liquids from penetrating inside the structure and staining the concrete. The causes of these cracks can be due to variations in air temperature, concrete temperature, relative humidity, and wind speed on the concrete surface.
