Most of the concrete that is in circulation and used today is made with Portland cement This was invented in 1824 by an Englishman named Joseph Aspdin named so since it resembled the high quality building stones found on the Isle of Portland in Dorset He refined his method for making this cement by meticulously proportioning limestone and
The invention of Portland cement revolutionized the construction industry allowing for the creation of structures that were much stronger and more durable than those that had been built before This new cement was used to build structures such as the Hoover Dam the Panama Canal and the Empire State Building which still stand today as a

Baker [1903] describes this pavement system as 1 a wearing course 40 to 50 mm thick composed of asphalt cement and sand 2 a binder course about 40 mm thick composed of broken stone and asphalt cement and finally 3 a base layer of hydraulic cement concrete or pavement rubble old granite blocks bricks etc
Concrete certainly came of age in the last century in fact concrete is the most used man made material on the planet Yet the man who made it all possible is barely known or was until the publication of Concrete Century; Julius Kahn and the Construction Revolution This new book tells the story of how a young Detroiter solved a problem that
Modern concrete is due to the invention of Portland Cement in 1824 by Joseph Aspdin Joseph called the product Portland cement because he believed set mortar made from it resembled the best Portland stone and Portland stone was the most prestigious building stone in use in England at the time says Stuart Galloway President 20/20
Although the date Portland cement was invented is not known its patent was obtained by J Aspdin in 1824 Although the optimum heat treatment applied in the production of Portland Cement produced today ensure superior features to the cement produced by J Aspdin he should be recognized in literature as the person who invented cement
In 1824 Joseph Aspdin invented Portland cement by burning finely ground chalk and clay until the carbon dioxide was removed Aspdin named the cement after the high quality building stones quarried in Portland England In the 19th Century concrete was used mainly for industrial buildings
