In 1824 Joseph Aspdin, a British stonemason, obtained a patent for a cement he produced in his kitchen. The inventor heated a mixture of finely ground limestone and clay on his kitchen stove and ground the mixture together into a powder to create a hydraulic cement-one that hardens with the addition of water. He named the product Portland cement because it resembled a stone quarried on the Isle of Portland, off the British coast. With this invention, Aspdin laid the foundation for today's Portland cement industry.
