"History & Manufacture of Portland Cement


In 1824, Joseph Aspdin, a British stone mason, obtained a patent for a cement he produced in his kitchen. The inventor heated a mixture of finely ground limestone and clay in his kitchen stove and ground the mixture into a powder create a hydraulic cement-one that hardens with the addition of water. Aspdin 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."

I have no 'set' ideas on the matter on anti- cementism.
* Foundation...nice one eh!..lol
