Fly ash bricks are made using fly ash and water. The fly ash bricks have better properties than clay bricks and resistant to freeze thaw cycles. These bricks have high concentration of calcium oxide which is used in cement production and due to this it is called selfcementing brick. The fly ash bricks are lightweight and it reduces the weight of structure fly ash brick making machine.
plant sludge and Fly ash against fired clay bricks. Bricks so formed have adequate crushing strength, hardness and water absorption.
The manufacturing process for these bricks, known as fly ashlimegypsum bricks, required intimate mixing of fly ash, sand, lime and gypsum. Gypsum and lime were first ground to fine particles and then fly ash and sand added to make a fine blend.
cement content. Since the fly ash bricks consist of mainly two components, fly ash and cement, not only does fly ash become a filler material in bricks, but it also has a hydration reaction with calcium hydroxide generated by hydration of cement. The more cement content increases, the more fly ash content reacts with hydration products of cement.
Aug 23, 2012· Economic Concerns Currently, the demand for bricks is very high from the supply. Demand and Supply gap is around 250 billion bricks per annum. Raw material used for regular red brick is limited. In India, the annual production of Fly Ash can result in manufacturing 780 billion bricks. To reduce the demand and supply gap, we will need to expand in this sector at a larger rate than what is undergoing .
In Manufacturing Fly Ash Bricks : Along with pozzolanic properties, flyash also has ceramic properties due to which it is widely used in the manufacturing of fly ash bricks. Bricks produced from flyash are generally superior in quality and have high compressive strength compared to ordinary clay bricks.
Fly Ash Bricks Manufacturing Process. Firstly, raw material processing. The commonly used lime is the lump of lime, which needs to be processed by crushing and grinding before it can be put into use.
