Obsidian is an igneous rock. Rocks are not man-made. Man-made substances that are similar to rock include concrete and cement.
It is man made. The basic ingredients are limestone and clay which are roasted in a kiln.
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.
Man made solid structures are structures that humans have built. Examples of man made solid structures are dams, brick walls and concrete and cement blocks.
The two main man-made silicates are glass and cement. Glass is made by melting sand and other ingredients together, while cement is produced by heating a mixture of limestone and clay to high temperatures.
Cement bricks are made of Cement- it's in the name.

No, concrete is not a rock. Concrete is a man-made material composed of a mixture of cement, water, and aggregates such as sand and gravel. Rocks are naturally occurring solid materials composed of minerals.
No, cement is not organic. It is a mixture of minerals, primarily limestone, clay, and silica, that is processed at high temperatures to form a hard substance. Organic materials are derived from living organisms, whereas cement is a man-made product.
Cement is man made product invented by the Ancient Romans. So, yes it is abundantly available all the time because all you need to do is buy a sack of it at the hardware store.
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.
