Bitumen is a mixture of organic liquids that are highly viscous, black, sticky, entirely soluble in carbon disulfide, and composed primarily of highly condensed polycyclic aromatic hydrocarbons. Naturally occurring or crude bitumen is a sticky, tar-like form of petroleum which is so thick and heavy that it must be heated or diluted before it will flow. At room temperature, it has a consistency much like cold molasses.[1] Refined bitumen is the residual (bottom) fraction obtained by fractional distillation of crude oil. It is the heaviest fraction and the one with the highest boiling point, boiling at 525&_160;°C (977&_160;°F). In British English, the word 'asphalt' refers to a mixture of mineral aggregate and bitumen (or tarmac in common parlance). The word 'tar' refers to the black viscous material obtained from the destructive distillation of coal and is chemically distinct from bitumen. In American English, bitumen is referred to as 'asphalt' or 'asphalt cement' in engineering jargon. In Australian English, bitumen is sometimes used as the generic term for road surfaces. In Canadian English, the word bitumen is used to refer to the vast Canadian deposits of extremely heavy crude oil,[2] while asphalt is used for the oil refinery product used to pave roads and manufacture roof shingles. Diluted bitumen (diluted with naphtha to make it flow in pipelines) is known as dilbit in the Canadian petroleum industry, while bitumen "upgraded" to synthetic crude oil is known as syncrude and syncrude blended with bitumen as synbit.[3] Most bitumens contain sulfur and several heavy metals such as nickel, vanadium, lead, chromium, mercury and also arsenic, selenium, and other toxic elements. Bitumens can provide good preservation of plants and animal fossils.

1. Techniques and Requirements for Structural Waterproofing
October 14, 2009
A waterproofing system is required in a structure because a structure is not water tight on its own. It is made up of certain materials that absorb water or are not resistant to it. Water seepage might have serious implications on a structure?s standing capability and life. Water can cause very serious damaging effects. It causes dampness, leakages, spoils paints, rusts products of iron etc. Conventional system of structural waterproofing involves use of membranes. The membranes are layered e.g. materials like bitumen, silicate, PVC, EPDM etc.They act as a barrier between water and the structu... (read more)

2. Concrete Batch Mix Plant
October 02, 2009
RMC or Ready mixed concrete or concrete is manufactured at a batching plant or factory. The mixed concrete is made to a set recipe, and then delivered to the desired workplace/worksite by the help of transit mixers. This results in ready mixed concretes which have a precise mixture, and this helps achieve specialty concretes to be developed and used on the construction sites. Today, RMC plants are playing a very important role in building road and civil structures. These RMC batching plants offer unmatched rigidity and long life to the structure. Hence it is getting popular and the use of ... (read more)

10. Oil from Ancient Times
February 10, 2008
Many people are surprised to hear that we’ve been using oil for almost seven thousand years. At first, we used oil that seeped to the surface in the form of thick black tar. In the Middle East, there is a huge oil reserve underground. In this area, there have been enormous oil seeps of bitumen, oil springs and oil-bearing rock. Oil has been readily available for use in this area since ancient times.
Oil was even effectively used in the time of the caveman. During the Stone Age, man used the bitumen tar to repair pottery and to seal water containers so that they would not leak. Oil and ta... (read more)

11. Oil Sands from Athabasca
February 03, 2008
Northern Alberta, Canada is the location of a very large, rich oil sand field. The Athabasca oil sands are named for the Athabasca River, where the oil sands are easily seen from the river banks. One third of the world’s oil sands are found here in Alberta, Canada and in Venezuela. The Athabasca oil sands field is unique in that the oil sands are located very near the surface and can be easily surface mined. This makes it much cheaper to mine, and makes Athabasca the leading provider of oil sands in the world.
Oil sands are a solid form of oil also known as tar sands. They are made up of ... (read more)

12. Will Alberta's Oil Sands Go Nuclear?
May 23, 2007
While the idea has been discussed and debated since the oil sands has come into existance, it looks as though Alberta's oil sands could finally be turning to, of all things, nuclear power to satisfy the outrageously large demand for electricity. The ambitious project, spearheaded by the local subsidiary of a mega-conglomerate, is focused on loosening up large quantities of bitumen encased in limestone. As usual, both investors and environmental activists looking for up-to-the-second facts and opinion are turning to the blogosphere. NEI Nuclear, a well-respected blog that offers ne... (read more)

14. Uses of Bitumen: Since Ages
July 14, 2006
If we look at all the chemicals that man uses for his daily living in the 20th century, we are likely to find that they are in the vast majority derived from one single substance - petroleum. This is certainly true in modern agriculture, in medicine, and in the textile industry - where both the dyes and the fibers themselves are synthetics made from various treatments of crude oil. Bitumen is one of them.
Bitumen is a generic term referring to flammable, brown or black mixtures of tar like hydrocarbons, derived naturally or by distillation from petroleum. It can be in the form of viscous ... (read more)
