The story of cement manufacture
CEMENT MANUFACTURE The cement-making process can be divided into two basic steps: Clinker (the main constituent of cement) is first made in a kiln with gas up to 2000C, which heats raw materials such as limestone (calcium carbonate) with small quantities of other materials (e.g. clay) to 1,450C.

The Suitability Of Limestone Aggregates For Use In Structural Concrete
Limestone Aggregate in Asphaltic Concrete. Limestone aggregate is also generally suitable for use in Asphaltic Concrete and is economically feasible when the absorption is relatively low (Less than 2.5%). High absorption rates may result in added asphalt binder needed to allow for asphalt absorbed by the aggregate.
