Crazing
Crazing is a network pattern of fine cracks that do not penetrate much below the surface. Crazing cracks are very fine and barely visible except when the concrete is drying after the surface has been wet. Although crazing cracks are unsightly and can collect dirt, crazing is not structurally serious and does not ordinarily indicate the start of future deterioration.

Steps to prevent Crazing:

1. Curing procedures should begin early.
2. When the temperature is high and the sun is out, some method of curing with water should be used.
3. The concrete should be protected against rapid changes in temperature and moisture when feasible.
