Starting around 5600 BC, the ancient Romans began using a material that was very similar in composition to modern concrete. They used this form of concrete to build the Colosseum, the Parthenon, and other structures.
Concrete is typically composed of ground up rocks, sand, and fly ash that is then mixed and held together with a binding agent. Don’t think that concrete flooring will resemble and feel like the sidewalk in front of your house. Because it is man-made, concrete flooring can be customized. It is available in multiple colors, textures, and patterns. It can also be polished, stamped, or painted. Decorative items like stones, tiles, or glass chips can be imbedded into the surface for an even more distinctive look.
Pros: Concrete floors are durable and easy to clean. It is also compatible with radiant heat.
Cons: Concrete is porous and will need to be periodically sealed. It can also be uncomfortable to stand on.
