Most of us often confuse cement with concrete as they are very closely related to each other. Cement is a binding substance which, when mixed with various other materials will bind & hold them tight together where as on the other hand concrete is a building material mix comprising of sand, gravel combined with cement and water to bind. Concrete is a very hard stone like substance often used as a primary building component in various architectural constructions. Concrete Cutting Melbourne experts presents some facts about Cement:
History of Cement- The word ‘Concrete’ is derived from the Latin word ‘Concretus’ which means “compact or condensed”. The Egyptians are said to have invented the early version of cement with a mixture of lime, sand and gravel containing gypsum which they used in building the famous pyramids. The Romans engineers also remarkably used cement like material to built many huge domes and concrete architectures such as Pantheon, Colosseum etc. In the medieval time the masons and the engineers often used this earlier cement containing gypsum to built canal, fortresses, harbors and ship building facilities. In the late 18th century the French & British engineers started experimenting and later developed the Portland Cement that we all use today.
Portland Cement- In 19th century a British mason known as Joseph Aspdin invented the present day cement by heating a mixture of clay and limestone and making it into a fine powder which when mixed with water solidifies and forms a very hard structure. This was World’s first hydraulic cement.
Portland cement is the most common type of cement used around the world in the production of concrete for building & construction purposes.
Forms & Types- Cement comes in two forms Hydraulic and Non-Hydraulic cement. Hydraulics cement when mixed with water, the hydration chemical reaction between them hardens the mixture resulting into a rock solid water resistant structure which is mostly used for any kind of construction purpose. Non-Hydraulics cements doesn’t reacts to water and thus they do not solidifies when exposed to water so they are seldom used as a building material.
The most common type of Cement today is the Ordinary Portland Cement made by grinding s aluminosilicate minerals and sintered limestone and into a very fine powder. They have very high compression strength and very fast drying rate which makes them very ideal for architectural constructions and generally used in production of concrete, mortar, grout, and stucco.
