Who invented the Cement?

The invention of cement, particularly the modern type known as Portland cement, is attributed to Joseph Aspdin, an English bricklayer and builder. In 1824, Aspdin patented a method for producing a hydraulic cement by burning a mixture of limestone and clay to create a product that, when mixed with water, would set and harden. He named it “Portland cement” because the hardened cement resembled Portland stone, a type of high-quality building stone quarried on the Isle of Portland in Dorset, England.
