This lesson goes over the biography of Joseph Aspdin, the inventor of something called Portland cement. Rarely do we think of Aspdin. You probably never heard of him but he is the inventor that made modern infrastructure possible all over the world.

Buildings, sidewalks, bridges highways and much more are built so well partly as a result of his most important invention, Portland cement. He was the eldest of six children born to Thomas Aspdin a bricklayer and Mary Aspdin. Aspdin started out like his dad, as a bricklayer and for some time lived at No. On May 21, , Aspdin married Mary Fotherby.

They had several children, including two sons and somewhere between daughters although two died during infancy. Joseph Aspdin died a wealthy man on March 20, in Wakefield and was buried on the grounds of St. About His Invention After , Aspdin began to experiment with cement, although some records exist that he did so as early as Regardless, through experimentation and some luck he eventually came upon his invention and on October 21st, was granted a patent, British Patent , for an improvement in the mode of producing an artificial stone.

Aspdin used the term Portland cement in his patent. This type of stone was quarried in an English peninsula near a town called Portland in Dorsetshire. This mixture would be heated at very high temperatures in a kiln and then crushed into a fine powder thereafter to make the end product. The exact proportion of what was mixed, when and how it was heated was not indicated in his patent.

Not long after getting his patent, Aspdin formed a business with a neighbor known as William Beverley. They founded a factory in Kirkgate, Wakefield that made Portland cement. Apparently, they ran their operation with great secrecy to ensure no one stole their idea, as even workmen in their factory only had the vaguest notion of what they were doing and why.
