Most limestone is made into crushed stone that is used in road base, railroad ballast, foundation stone, drainfields, concrete aggregate, and other construction uses. It is fired in a kiln with crushed shale to make cement. Some varieties of limestone perform well in these uses because they are strong, dense rocks with few pore spaces.
Calcium oxide which is accessible from limestone mines is the most important requirement for generating a suitable raw mix for cement plants. To attain a balance of silica (SiO 2), alumina (Al 2 O 3), and iron, secondary raw materials are necessary (Fe 2 O 3).
