The History Of Concrete And Various Forms Of Concrete
Posted by ama | Filed under New Construction
The word concrete is derived from a Latin word ‘concretus’ which means to compact or condense.Concrete is a material used for construction and usually consists of cement, gravel, sand and water.It is one of the most employed man-made materials used in the construction of a variety of structures.This material is also made use of for the building of pavements, foundations, motor roads, brick walls, parking spaces and in many other building projects.
There is no industry more expansive than this having almost $35 million as its net worth and employees over 50,000 in the United Kingdom alone.With a view to improving the standards of construction there are many of the concrete trade association that have laid down some of the criteria that every construction including residential and commercial buildings have to adhere to. To give an idea of these kinds of association a few names are mentioned here – The British Ready Mix Concrete Association, The Concrete Repair Association, The Sprayed Concrete Association and The Concrete Block Association.
One can trace back the use of concrete to as old as the one used by the Babylonians and Assyrians in a clay mould similar to the concrete.This has been used by a lot of other early civilizations.Even in the construction of the Egyptian pyramids one has investigated the use of concrete.
There has been proof of usage of the concrete by the Romans also.Even in the Roman structures one can see that there has been use of the concrete that makes them one of the most popular structures in the entire world.It is the use of concrete to build about 5,300 miles of roads for them.
Modern concrete (various forms)
In the year 1756 for the first time John Smeaton (a British engineer) made use of the concrete to build a latest form.He made the foremost contemporary concrete, which was called hydraulic cement and which was nothing but an amalgamation of a coarse aggregate of pebbles and cement mixed with powdered bricks.This was done with a view to improving the conduction of electricity along with providing long term stability.
It was a mixture of lime and clay that was invented later on called the Portland cement in 1824 by Joseph Aspdin.It has been the most dominant version of concrete since then.
In 1849, Joseph Monier invented reinforced concrete and also obtained a patent in it in 1867.Reinforced concrete was specifically used to hold out heavy loads as it contained iron mesh.This form of cement has been used in the construction of bridges, railway lines and pipelines.
In today’s times as most of the people know the effects of environmental squalor they try to make use of the recycled materials with the concrete.
Compositions of concrete
Inspite of the complex cities involved in the composition of the new concrete than the older one they have been proved to provide permanence and stability.Following are some of the ingredients used in concrete:
It is cement that is the vital element in concrete.The most popular cement in distribution these days is Portland cement which is nothing but a blend of plaster and mortar.
One more portion of the concrete is the Aggregate that is made up of gravel, sand, burned clay and crushed stone.
Another major constituent of the concrete is water that helps in its functioning.A less ratio of water as compared to cement will make the concrete stronger and vice versa. Author is an expert on various construction topics and find more articles on Concrete and Trade Associations.
