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.

How does Portland cement differ chemically from other cement?
I assume you are contrasting portland cement with fly ash to portland cement with powdered slag? (Fly ash is from coal furnaces, powdered slag is from oil-burning furnaces). Slag is very similar to portland cement, and can be used to cheaply replace up to 50% of portland cement in concrete. This is less expensive, and the slag makes the hardened concrete more resistant to de-icers. Fly ash is not similar to portland cement, but is also good to resist de-icers. But since fly ash is not similar to portland cement, only 20 to 30% of portland cement can be replaced by it. The main difference in chemistry are the amounts of oxygen-containing elements. (Called 'oxides'). For example, portland cement has 65% of C2O, Slag cement has 45%, and Fly ash contains 25% For SiO2 portland cement 20%, Slag cement 33%, and Fly ash 37% For Al2O3 portland cement 4%, Slag cement 10%, Fly ash 16%. There are other very minor differences in chemistry.
