Understanding Limestone in Cement| Concrete Construction
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

How Cement Is Made
Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with

CEMENT RAW MATERIALS
The overburden to limestone deposits is also used frequently as a source of silica, alumina and iron. Other mineral components (such as iron oxide wastes, silica sand, etc) are sometimes used to blend into the raw material mix to optimise the chemistry. The variety of raw material used worldwide for cement manufacture is very great.

What is the role of lime in cement?
Consequently, what is the purpose of lime in cement? Lime has been used as a binder in mortars for over 2000 years. Today, lime is still used as the primary binder in many mixes, usually in the form of lime putty or Hydraulic lime. Hydrated lime is used in modern cement based mortars mainly for its properties as a plasticiser.
