eco friendly fly ash bricks | eco friendly living

Today we discuss eco friendly fly ash bricks.Have you ever wondered what happens to the ashes from your fireplace? Or the ashes from a barbecue grill? Traditionally, these ashes have been dumped into landfills, but there is now a better way to handle them. learn about eco friendly fly ash bricks and how they are made.

different sizes of fly ash bricks:

There are generally four different sizes of eco friendly fly ash bricks: 4 inch, 6 inch, 8 inch, and 12 inch. However, the dimensions of each brick can vary slightly depending on the manufacturer.

For example, one manufacturer may produce a 6 inch brick that is actually 6.25 inches long, while another may produce a 6 inch brick that is only 5.75 inches long. So it’s important to check with your supplier to make sure you’re getting the size of brick you need for your project.

process of making fly ash bricks:

eco friendly fly ash bricks are made by mixing fly ash, lime and water. The mixture is then poured into molds and allowed to set.

Fly ash is a by-product of coal-fired power plants. When coal is burned, it produces a lot of ash. This ash contains a lot of silicon dioxide, which is what makes fly ash bricks strong.

Lime is used to make the fly ash more alkaline. This helps to control the setting time of the mixture and also makes the bricks less brittle.
Water is used to make the mixture wet enough so that it can be poured into molds.

fly ash bricks vs concrete blocks:

  1. Fly ash bricks are made of fly ash, lime, and water. Concrete blocks are made of portland cement, aggregate, and water.
  2. Fly ash bricks have more compressive strength than concrete blocks.
  3. Fly ash bricks have less absorption than concrete blocks.
  4. Fly ash bricks are more uniform in shape and size than concrete blocks.
  5. Fly ash bricks are easier to cut than concrete blocks.

role of gypsum in fly ash bricks:

Gypsum is one of the main ingredients in Fly ash bricks. It is used as a binding agent to hold the bricks together. Gypsum can also help to control shrinkage, and it gives the bricks strength and durability. Gypsum gives fly ash bricks their fire resistant properties, which is why it is often used in construction applications.

eco friendly fly ash bricks density:

eco friendly fly ash bricks are made from a combination of fly ash, cement and water. fly ash bricks mixing ratio are typically around 80% fly ash, 10% cement and 10% water. The fly ash used in the bricks can vary depending on the type of coal burnt to generate electricity at the power plant, but is usually around 50-70%.

Bricks made purely from fly ash can have a density of around 1600kg/m3. However, because Fly ash bricks are only around 80% fly ash, the actual average density of fly ash brick is therefore only 1280 kg/m3. This compares to an average red brick density of 1800kg/m3. So while Fly Ash Bricks are lighter when compared to clay bricks.

fly ash brick advantage and disadvantage:

When used in bricks, fly ash saves energy and resources required for firing clay, reduces greenhouse gas emissions, and uses waste materials that would otherwise be considered pollutants.

Whilst fly ash bricks offer many advantages, there are also some disadvantages to consider. Due to their lower density, fly ash bricks are not as strong as clay bricks and may not be suitable for load-bearing applications.

In addition, the manufacturing process for fly ash bricks is currently more expensive than traditional brick production. However, as fly ash bricks become more widely used, it is likely that the cost will decrease.

Fly ash bricks are an excellent alternative to usual clay bricks. They offer many advantages, including energy savings, greenhouse gas reduction, and the use of waste materials that would otherwise be considered pollutants.

While there are some disadvantages to consider, such as strength and cost, fly ash bricks are a great option for many applications.

bottom ash vs fly ash:

Bottom ash is the heavier, coarser portion of the coal that falls to the bottom of the furnace during burning. Bottom ash is cinema-graphically represented as the layer of grey sludge lining the bottom of a typical coal-fired power plant.

Fly ash, on the other hand,is much finer and lighter than bottom ash. It’s composed of very small particles that are suspended in air and rise up out of the furnace with the flue gases. Fly ash typically makes up between 15 and 20 percent of power plant emissions.

fly ash brick wall construction:

1. is bottom ash is perfect for making bricks?


No, bottom ash is not perfect for making bricks. While it can be used for this purpose, there are better materials available. Bottom ash is a byproduct of coal-fired power plants and contains high levels of metals and other toxins that can be harmful to both people and the environment.

2. is wet ash is perfect for making bricks?


Yes, wet ash is perfect for making bricks. because of the wet ash strengthens the bond between the bricks, which makes them less likely to crumble or crack over time.

plus, wet ash prevents moisture from seeping into the brick, which can cause it to degrade. Finally, wet ashes high concentration of minerals gives brick made with it a more textured and interesting look. clay ash bricks and fly ash bricks have the same strength?


The two types of bricks have different strengths because they are made from different materials. Clay ash bricks are made from clay and ash, while fly ash bricks are made from fly ash and lime.

Fly ash is a by-product of the burning of coal, so it is more common than clay ash. Fly ash bricks are stronger than clay ash bricks because they contain more cement.

4. what is the fly ash bricks size in mm?


The size of a fly ash brick depends on the manufacturing process. However, in general, fly ash bricks dimensions are around 150 mm x 100 mm x 65 mm.

5.what is the fly ash bricks material ratio?


According to a study by the Central Building Research Institute (CBRI), the ideal ratio of fly ash to other materials in eco friendly fly ash bricks is 70:30. However, the actual ratio can vary depending on the type of clay and other additives used.

The most important thing is to ensure that the bricks have enough fly ash content to be durable and fire resistant.

6. what types of lime for fly ash bricks is necessary?


the most common type of lime that is used is calcium oxide. This type of lime is perfect for creating fly ash bricks because it helps to bind the material together and it also helps to improve the strength and durability of the bricks.

besides this, calcium oxide is also known for its ability to resist water damage, so it’s a great option for those who want a long-lasting brick.
types of eco friendly bricks


eco friendly fly ash bricks are a great alternative to traditional clay or concrete bricks. They are made of up to 70% fly ash, a waste product from thermal power plants, and lime. This makes them an excellent choice for construction projects that aim to be more sustainable.

fly ash bricks have many other benefits over traditional bricks including increased strength, insulation, and moisture resistance. If you’re looking for an environmentally friendly option for your next construction project, consider using fly ash bricks.
