“Portland Cement History and its Development” Portland cement, definitely one of mankind’s most important manufactured materials, was invented and patented by Joseph Aspdin from Leeds in 1824. Aspdin produced cement by heating powdered limestone mixed with clay in a furnace, and grinding the resulting clinker to form it to powder. He called the product “Portland Cement” because of its similarity, when set, to Portland stone, a type of stone quarried on the Isle of Portland. Aspdin’s cement was improved in 1843 by his son William, by strong heating and using better grinding equipment to handle the hard clinker. Until nowadays, Portland cement is still the most commonly used cement around the world.
