May 09, 2012· The primary component of cement is limestone. To produce cement, limestone and other claylike materials are heated in a kiln at 1400°C and then ground to form a lumpy, solid substance called clinker; clinker is then combined with gypsum to form cement. Cement manufacturing is highly energy and emissionsintensive because of the extreme heat required to produce it.

The use of limestone in the construction industry has been increasing due to benefits as aggregate. Some of these benefits include good strength, low possibility of alkalisilica reaction and the decrease in drying shrinkage in concrete. This research discusses the consumption and general characteristics of the limestone aggregate in USA and Japan.

One of the largest cement plant in the state is in Alpena. Crushed stone Most crushed stone is limestone and dolomite. It is used mostly for construction purposes, although much of it is also used in shoreline protection. In construction, crushed stone is used as an aggregate in concrete mixes. The stone binds the mix together when it hardens.
