- Abstract
- The firing of stone or clay to produce cementing materials for construction is as old as recorded history. The ancient binders - lime, hydraulic lime, gypsum and certain volcanic rocks (pozzolana) - are still in use, but today they are far overshadowed by portland cement, a highly sophisticated relative of hydraulic lime.
