But every one have their different thoughts and opinion so everyone wants to know the real facts of what ever they are going to buy, and here we are posting the clear facts to know about the fly ash bricks.
Give your 5 minutes read on this post to get clarified about the fly ash bricks and take a choose the best quality of flyash bricks in Coimbatore from our Udayam flyash bricks.
Flyash Brick is a building material components which consists class C or F type fly ash and water.
This fly ash bricks can withstand over 100 freeze-thaw cycles. Due to the high concentration of calcium oxide in Class C fly ash, the brick is said to be “self-adhesive”.
This manufacturing method saves energy, reduces mercury pollution in the environment, and often costs 20% less than traditional brick manufacturing.
The strength of flyash bricks made with the above composition ranges from 7.5 MPa to 10 MPa . Fly ash bricks are lighter and stronger than clay bricks. The main ingredients of flyash bricks are fly ash, water, quicklime or lime slurry, cement, aluminum powder, and gypsum.
Autoclaving increases the hardness of blocks by promoting rapid hardening of cement. Gypsum acts as a long-term strength enhancer.
A chemical reaction [further explanation needed] with the aluminum paste gives AAC its unique porous structure, lightness and thermal insulation. The properties mentioned set it apart from other lightweight concrete materials.
The finished product is a lightweight block that is less than 40% lighter than traditional bricks and has similar strength.
Specific gravity remains around 0.6 to 0.65
Using these blocks in buildings reduces the dead load, allowing one to save around 30 to 35%[citation needed] of structural steel, and concrete.
Commercial processes fall into two categories; the lime route, and the cement route where the latter is used as a source of lime.
In the lime route, the composition is fly ash – 50%), slaked lime – 30%, and anhydrous gypsum – 20%, to which 3 to 4 times of stone dust, sand or any inert filler material can be added. In the cement route, the composition is fly ash(76%), OPC (20%), and anhydrite (4%), to which 3 to 4 times of filler material can be added.
The following properties of fly ash affect the strength and look of fly ash bricks.
Ignition losses: Due to the presence of carbon and water, fly ash loses weight when burned at about 1000°C. Weight loss is caused by the combustion of carbon and the evaporation of water and is called “Loss on Ignition”.
This is expressed as a percentage. The lower the ignition loss, the better the fly ash, according to BIS, it should not exceed 5%.
Fineness: Fine fly ash provides more surface area to react with lime. This increases the pozzolanic activity that contributes to the strength of fly ash bricks. According to BIS it should not exceed 320 m2/kg.

Calcium content: The pozzolanic reactivity of flyash bricks in coimbatore is stronger for fly ash with higher calcium content. The higher the pozzolanic activity, the stronger the fly ash bricks.
