    This heat perpetuates the reaction until the mix is saturated with the ions, at which point the calcium hydroxide begins to crystallise forming a more rigid structure. Crystals of calcium hydroxide begin to thicken making it harder for the water to reach the unhydrated tricalcium silicate. Therefore the reaction slows as the mixture sets.

    To make cement, crushed limestone and shale are heated to a temperature that is high enough to evaporate off all water and break down the limestone into calcium oxide and carbon dioxide. The carbon dioxide is lost as an emission, but the calcium oxide combined with the heated shale makes a powder that will harden if mixed with water and allowed to dry. Cement is used to make concrete and many
