Portland cement got his name derived from the appearance of concrete that resembles sandstone located near city of Portland in England. In 1824, John Aspdin was granted a patent for the production of Portland the past, energy and economic demands on production of cement were lower than they are today. Production was characterized by a slower burning mode and coarser grinding.
