Although put together by humans, the parts of cement are natural. Cement is a fine, soft, powdery-type substance. It is made from a mixture of natural rocks: limestone, clay, sand and/or shale. When cement is mixed with water, it can bind sand and gravel into a hard, solid mass called concrete.
It is man made. The basic ingredients are limestone and clay which are roasted in a kiln.
Concrete is a man-made material that is produced by mixing cement with aggregates and water. It is not a natural resource, but rather a construction material that is widely used for building structures.
Cement is a man-made material produced by heating and grinding together a mixture of limestone and clay. It is not generally considered a natural material due to the extensive human processing involved in its production.
Concrete is a man-made material. It is created by mixing cement, water, and aggregates like sand and gravel. While some of its components, such as sand and gravel, are natural materials, the process of combining and curing them to form concrete is entirely artificial.
It is natural but there are man-made imitations.

Man-made and Natural Resources
Obsidian is an igneous rock. Rocks are not man-made. Man-made substances that are similar to rock include concrete and cement.
No "NATURAL" calamities are man made.
