The Caspian Sea region, which includes Russia, Azerbaijan, Kazakhstan, Turkmenistan, Uzbekistan, and , is one of the oldest oil-producing areas in the world and is an increasingly important source of global energy production.The area has significant oil and natural gas reserves from both offshore deposits in the Caspian Sea itself and onshore fields in the region.
Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
Our construction aggregates are used in a number of ways. As a base material underneath highways, walkways, airport runways, parking lots and railroads. To aid in water filtration, purification and erosion control. As a raw material used in combination with other resources to construct many of the items we rely on to sustain our quality of life.

Oil sands, tar sands, crude bitumen, or more technically bituminous sands, are a type of unconventional petroleum deposit.Oil sands are either loose sands or partially consolidated sandstone containing a naturally occurring mixture of sand, clay, and water, saturated with a dense and extremely viscous form of petroleum technically referred to as bitumen (or colloquially as tar due to its ...
Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.Over 60% of all metal castings are produced via sand casting process.
Asphalt paving material is a dull black mixture of asphalt cement, sand, and crushed rock. After being heated, it is dumped out steaming hot onto the roadbed, raked level, and then compacted by a heavy steamroller. Asphalt is also used for expansion joints and patches on concrete roads.
