The History of Portland Cement. Cement as we know it was first developed by Joseph Aspdin, an enterprising 19thcentury British stonemason, who heated a mix of ground limestone and clay in his kitchen stove, then pulverized the concoction into a fine powder. The result was the world's first hydraulic cement: one that hardens when water is added.
