Portland cement is made through a precise manufacturing process involving mining and grinding raw materials like limestone and clay, heating them in a kiln to form clinker, and then finely grinding the clinker. There are two main processes - the dry process mixes dry raw materials before heating while the wet process mixes materials into a slurry.
