When, in 1852, the idea of utilizing the English invention of the manufacture of Portland cement first appeared in Germany, no one anticipated the growth this industry was destined to have, a growth which soon outstripped that of the mother-country, England. As early as 1824, Joseph Aspdin, of Leeds, made a hydraulic lime by calcining a certain mixture of slaked lime and clay, which on account of its resemblance in color and hardness to the Portland stone, much valued at that time in England, he called Portland cement. The English product was soon introduced into Germany, and for a long time was considered unequaled. Not till 1852 was attention directed to the occurrence of the septaria clay in Pommerania, on the banks of the Oder, which was declared by Dr. Hermann Bleibtreu, of Bonn, to be suitable material for the manufacture of cement.
