Aspdin created the first true artificial cement by burning ground limestone and clay together. The burning process changed the chemical properties of the materials and allowed Aspdin to create a stronger cement than plain crushedJoseph Aspdin - Portland Cement,From Mississippi State Geological Survey - Bulletin 1 (1907) Portland cement was first made in 1824 by Joseph Aspdin, a bricklayer in Leeds, England. The name "Portland" was chosen because of the resemblance of the cement to the oolitic limestone of Portland, England. The limestone is extensively used in England as a road metal and building stone.Introduction to Concrete - Portland Cement Association,The development of portland cement was the result of persistent investigation by science and industry to produce a superior quality natural cement.
