In 1824, the English inventor Joseph Aspdin invented Portland Cement, which has remained the dominant form of cement used in concrete production. 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 crushed limestone would produce.
