ABOUT CEMENT.

PORTLAND CEMENT IS NOT A BRAND, BUT A TYPE OF CEMENT USED ALMOST UNIVERSALLY TODAY IN NORTH AMERICA AND THROUGHOUT MUCH OF THE INDUSTRIALIZED WORLD. IT EMERGED IN THE EARLY 19TH CENTURY AS ONE OF THE MAJOR TECHNICAL DISCOVERIES OF THE INDUSTRIAL AGE.

In 1824, an English bricklayer patented the product. He called it "portland" cement because he thought it resembled natural building stone found on the Isle of Portland in the south of England. Today, portland cement, stone, sand and water are the basic ingredients of the concrete products with which we build highways, bridges, commercial buildings, dams, residential homes and many of the other structures fundamental to America鈥檚 economic vitality and quality of life.

The Portland Cement Association provides information on cement and concrete basics.
