What does crazing in concrete refer to?

Crazing in concrete refers to the appearance of fine cracks on the surface of the concrete, typically resulting from shrinkage or rapid drying. These cracks are usually shallow and can form in a pattern that resembles a spider web or a network of cracks throughout the surface. This phenomenon is often more pronounced in concrete slabs that have been troweled too early or in conditions where curing is insufficient, leading to uneven moisture loss.

Understanding crazing is important for builders and contractors because it can affect both the aesthetic quality and long-term durability of a concrete surface. Proper curing methods and avoiding rapid drying conditions are critical to minimizing the risk of crazing. Recognizing the signs and causes of crazing allows professionals to implement better practices, enhancing the strength and appearance of their concrete work.
