What are Fly Ash Bricks? Raw Materials Used in Fly Ash Brick Manufacturing


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 in specific proportions. 

The primary raw materials used in fly ash brick manufacturing are as follows:

1. Fly Ash  

            Fly ash is a fine powder produced as a by-product of coal-fired power plants. It serves as the main raw material in producing fly ash bricks.


2. Sand  

        Sand is added to the mixture to strengthen and stabilise the bricks. Additionally, it enhances brick polish and texture.


3. Sludge Lime  

        After treating industrial wastewater, sludge lime is produced as a waste product. It is employed in producing fly ash bricks to provide them with strength and durability.


4. Gypsum  

        Gypsum is added to the mixture to regulate brick curing duration. Additionally, it enhances brick use and appearance.


5. Grit 4 MM to 8 MM  

        Grit is added to the mixture to provide texture to the surface of the bricks. It also improves the bricks' strength and stability.


6. Crusher Dust 0 MM  

        Crusher dust is a waste product generated from stone crushing. It is used in the manufacturing of fly ash bricks to provide strength and durability to the bricks.


7. Cement 

        Cement is added to the mixture to provide binding properties to the bricks and improve their strength and durability. 

        Water is added to the mixture to provide the necessary moisture content for manufacturing. 

        It helps bind the raw materials together and allows for brick formation. 

            Combining these raw materials produces high-quality, cost-efficient, and environmentally friendly fly ash bricks. 

        Depending on the particulars of the production process, such as the required strength and texture of the bricks, the exact proportion of these elements will vary.

NOTCHES AND WEIRs

Image
   NOTCH ,WEIR AND ITS TYPES Notch A  notch  may be defined as an obstruction over which the flow of liquid occurs   In case of measuring tank or reservoir, the opening is provided at the side of the tank such that the liquid surface in the tank is below the top edge of the opening. Weir A  weir  is a notch on a large scale used for measuring the flow of a river, canal etc. It is a concrete or masonry structure of substantial breadth built across the river in the direction of flow. This allows the excess water to flow over its entire length to the downstream side. Thus a weir is similar to a small dam constructed across the river, with a difference that the excess water flows downstream only through a small portion called  spillway  and in case of weir, the excess water flows over its entire length. Nappe and crest The sheet of water flowing through a notch or over a weir is known as  nappe  or  vein . The bott...

THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS

 THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS The Basics of Rebar If you have ever wondered what gives strength and stability to the concrete structures that we see around us, the answer is (most commonly) rebar. Rebar, short for reinforcing bar, is the steel rods that are embedded in concrete that provide tensile strength to what is actually and prevent cracking. Rebar comes in different shapes and sizes, but the most common type is deformed steel rebar, which has ridges or indentations along its surface to create a better bond with the concrete. Deformed steel rebar has been used in the construction industry for over a century, and it has revolutionised the way we build. With rebar, and using elements such as beams,  beam ties , rebar mesh, and reinforced walls, we can create taller, stronger, and more durable structures that can withstand natural disasters, environmental changes, and human activities. Some of the most iconic buildings in the world, such as...
