History

In the Beginning 

A mixture of lime, clay, sand and water was used in very ancient constructions. The Egyptians were already using it 2,600 years ago.

Around the 1st century, the Romans perfected this "binder". From adding volcanic soil from the region of Pozzuoli, near Naples, they discovered that they could get this mixture to "set" under water.

We now know that the soil from Pozzuoli - which lends its name to pozzolan - is 60 to 90% clay and 10 to 40% lime, depending on the source. Archaeological vestiges from that time, such as cement drains, have been discovered in several Roman cities.

1817: Rebirth 

In 1817, the young engineer Louis Vicat was working on the hydraulic properties of a "lime-volcanic ash" mixture.

Louis Vicat was the first to determine in a precise, controlled and reproducible manner the proportions of limestone and silica needed to obtain a mixture which, after burning at a specific temperature and after grinding, produced a hydraulic binder for industrial applications. In other words, cement.

However, he published the results of his research without filing for a patent.

The 19th Century: Industrialization

Scotsman Joseph Aspdin refined the cement composition developed by Louis Vicat and, in 1824, filed a patent for a slower setting cement. He called it Portland, because it bore a resemblance to a type of rock found in the region of Portland in southern England.

The first cement plant in France was built in 1846 at Boulogne‑ sur‑Mer. In 1868, Lafarge began producing cement at Teil, in the Ardèche.

The use of cement soared with the advent of new, faster processes for cement manufacture.

Lafarge was responsible for two important discoveries that marked the early 20th century:

• the advent of white cement, which uses kaolin instead of clay. This cement offers the same resistance as a comparable grey cement but better aesthetic qualities;
• the discovery of Ciment Fondu® in 1908 by Jules Bied, director of the Lafarge research laboratory. This cement, made from limestone and bauxite, resists aggressive environments and high temperatures. It is very versatile and can be used as a high-performance binder or a chemical reactant in a diverse range of applications.

Today, Lafarge research and development continues to focus on innovation and works to continually improve the properties of cement.

Lafarge entered the Philippine cement market in 1998. Through its partnership with Republic Cement Corporation, the leader in cement production in the country since 1955, Lafarge markets cement products both in bags and bulk, under three brands -- Republic, Fortune and Mindanao.
