Portland-Limestone Cement
Crushed limestone is often the main raw ingredient in the manufacture of portland cement clinker that eventually becomes cement. Other raw material sources of calcium carbonate include shells, chalk or marl, which are combined with shale, clay, slate, blast furnace slag, silica sand or iron ore.

Limestone quarry, quarrying, cement raw materials
Since a form of calcium carbonate, usually limestone, is the predominant raw material, most plants are situated near a limestone quarry or receive this material from a source via inexpensive transportation. Cement manufacturing begins with quarrying operations in which limestone in mines is quarried and brought to crusher for crushing.

How is concrete made from limestone? | Shelly Company
To make Portland cement—the most common type of cement—powdered limestone is heated in a rotary kiln. As a source of calcium, it joins with powdered clay to produce a product called clinker, which is then ground with a source of sulfate, like gypsum. It is mixed with water, sand and crushed rock to create concrete.

Limestone Mining
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.

The Suitability Of Limestone Aggregates For Use In Structural
Because limestone aggregate is normally comprised of 100% crushed fragments, the better surface texture and higher angularity that obtains lead to good bond with the cement and good particle interlock, both of which help in achieving good compressive strength properties.

Crushed Limestone Concrete Aggregate
First, for a given amount of cement in the mix, crushed limestone concrete will have an approximately 10% strength advantage. This strength advantage comes from the fact that cement bonds tighter to limestone than to a slick/smooth gravel and the strength that is derived from the sharp angular faces of the crushed aggregate.
