The history of cement
The history of cement goes back to the roman era and being developed by other civilizations whereas they had used the gypsum and the cement was close to mortar cement than the current cement during the past time, cement as known is a mixer of gypsum, mod and buzzolana, in which the current cement became well known as it is now in the 19 century. In the year 1817, the scientist Louis Vicant had discovered the moisture mystery in the gypsum which was called the Hydrated Gypsum. • In 1840 discovered the theory of limited lime, this theory was based on the production of a type of lime cannot be hydrated by water which earns a greater hardness of the material at cohesion. In the year 1876 the scientist James Parker had discovered on SHAIBY island of
Great Britain the easy cement (Natural Cement with fast fusion) and he called it the
Roman cement. In 1924 the British scientist Joseph Aspalin consigned a patent for the manufacture of the hydrated lime and called it Portland cement in relative to the Portland Upper
Peninsula on the shores of the Munch Sea that separates France and Britain. The first cement plant invented by Dupont et demarlé in the year 1846 in Boulogne-
Sur-Mer area, and the cement industry had developed after the emergence of new materials such as (kinetic rotating kiln), clinker granules crusher, and thus cement industry and its equipment had developed and still ongoing. In 1870, to produceone ton of clinker (the main component of cement) takes 40 hours, but now it is only 3 minutes. The cement had improved and developed a lot and had a numerous types such as foam cement, light cement and fast solidification ... etc.
