advent of the rotary kiln is closely tied to the creation of Portland cement. In 1824, Joseph Aspdin successfully produced an eminently hydraulic lime by cooking at high temperature, in a bottle kiln, a mixture of limestone and clays; he referred to his output as "Portland Cement" [2-4]. The bottle kiln however displayed major flaws,
