What is Bitumen?                     Bitumen is a form of petroleum.  This material has a sticky and viscous form that makes it a suitable choice for wide applications in the construction industry.  Bitumen manufacturing process includes separating different components of petroleum.  This separation is based on the boiling point of each component.  This process is called bitumen distillation.  The outcome is a material called bitumen that gets widely used for road paving, waterproofing, and roofing applications. According to Infinity Galaxy, bitumen is mainly a composition of hydrocarbons.  However, in the bitumen manufacturing process, other materials are used, such as small amounts of nitrogen, sulfur, and maltenes.  It is also used in the asphalt refining process to provide the required durability for road construction.

What are Fly Ash Bricks?                Fly ash, cement, sand, and water are combined to create fly ash bricks. Burning coal in power plants produces fine, powdery fly ash.               It is collected by electrostatic precipitators and other pollution control devices before escaping into the atmosphere.               Fly ash is a waste material that can be tapped as a valuable resource for producing bricks.                  Using fly ash in brickmaking can reduce the environmental impact of coal-fired power plants and conserve natural resources like clay, traditionally used in brickmaking.         Raw Materials Used in Fly Ash Brick Manufacturing          The manufacturing process of fly ash bricks involves using several raw materials mixed together ...
