Historical Perspective for Concrete and Precast Concrete Building Construction
The Egyptians were using early forms of concrete over 5000 years ago to build pyramids. They mixed mud and straw to form bricks and used gypsum and lime to make mortars.
The ancient Romans used a material that is remarkably close to modern cement to build many of their architectural marvels, such as the Colosseum, and the Pantheon. The Romans also used animal products in their cement as an early form of admixtures. Admixtures, additions to the mix used to achieve certain goals, are still used today,
Joseph Aspdin of England is credited with the invention of modern Portland cement. He named his cement Portland, after a rock quary that produced very strong stone.
Types of Cement and What They Do
Portland Cement is a type of cement, not a brand name. Many cement manufacturers make Portland cement.
The Wide World of Cements
There are many different properties and applications of cements for use in concrete including portland, blended, and hydraulic cements.
