materials - concrete

Concrete is a mixture of Portland cement, gravel, and crushed rock mixed with water.

It is poured into a cast – often insitu (at the site) or made into concrete tiles. These can be square, or in a shape.

Traditionally used for pathways, and subflorring, but recently used as counter tops and flooring when sealed and polished.

It is naturally light grey, but can be dyed
