Historical Review

Cement substance was used early in the past when ancient Egyptians used burnt impure gypsum, and the Greek and Roman used lime with water, sand and broken bricks/stone bits which were the oldest concrete that history knew. Yet, when used under water, these materials proved unsolid. Consequently, the Greek used lime with the remnants of volcanoes and red bricks dust to be used in building under water. The active volcanoes substances Silka and Alumina used to react with lime and water to form pozzolana cement named after Pozzuoli city in Rome.

Cement industry began in the 18th century when JOHN SMEATON discovered that the best cement substance was to mix pozzolana or volcanoes dust with limestone that contains clay. Additionally, James Parker created the first artificial cement by burning ground limestone and powdering it; this cement was called Roman Cement.

In the early 19th century, the Portland cement was invented by Scientist Joseph Spin. This cement was manufactured by heating a mixture of clay powder with the limestone in a kiln till the carbonic acid is entirely expelled.

Portland cement was given that name as it is very close, in shape and color, to the natural stone found in the isle of Portland in Britain.
