THE HISTORY OF CEMENT
Throughout the ages, cement has been the main construction material used by mankind, because Portland cements and their by-products are basically a blend of limestone, clay and gypsum, which are minerals that are abundant in nature
The Coliseum of Rome contains concrete in the foundations, the inner walls and the structure.
Construction of major works such as the Salisbury Cathedral in England, whose foundations are made of concrete.
John Smeaton, a Leeds engineer in the UK, developed a new mortar to join the stone blocks of the Eddystone lighthouse. Within a few years, the Rev. James Parker created a new cement by accidentally burning limestone. This new cement, called Roman cement because it was thought to have been used in Roman times, was patented and began to be used in various works in the United Kingdom.
The industrialisation process and the introduction of rotary kilns led to the extension of its use for all types of applications.
Despite all the technical improvements introduced, Portland cement continues to be essentially similar to the first one that was patented, although its impact and performance have improved significantly.
