Why are surfaces of old concrete statues are often covered in small holes or pits?
The small holes or pits on old concrete statues are likely due to a natural process called spalling. This occurs when water seeps into the concrete, freezes, and expands, causing small pieces of the surface to break off over time. Additionally, environmental factors such as air pollution or weathering can contribute to the deterioration of the concrete surface.
