On the other hand, portland cement is an artificial mixture of raw materials, has a calcination at a temperature above 2,000 degrees Fahrenheit, and purer raw materials were used than necessary for natural cements. The raw materials used in the manufacturing of portland cement at this time were cement rock, limestone, shale, and coal. Cement is thought to be older than humanity itself, having formed naturally 12 million years ago, when burnt limestone reacted with oil shale. Concrete dates back to at least 6500 BCE when the Nabatea of what we know now as Syria and Jordan used a precursor of modern-day concrete to build structures that survive to this day.
