The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement. As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. The cement might have a reduced water demand, and the coarser cement gradation ...

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.
