Cement is often referred to as Portland cement, a generic term used for nearly all cement. It is the mixture from which many types of concrete are made and is called such due to its resemblance to a type of building stone quarried in the early part of the 19th century. This stone came from the Isle of Portland, located off the southern coast of England.
