What Is Fly Ash Brick? – How to Classify?
- Autoclaved fly ash bricks – Steam Curing
- Steam-Free and Burn-Free Fly Ash Bricks – Natural Curing
- Clay-Containing Fly Ash Bricks – Burned at High Temperatures
Everyone knows that fly ash can be used to make bricks, but you don’t know how to distinguish fly ash bricks.
So according to different raw materials, different curing methods.
It is divided into autoclaved fly ash bricks, steam and burn-free fly ash bricks, and burned fly ash bricks.
Autoclaved fly ash bricks – Steam Curing
Autoclaved fly ash brick is based on fly ash and quicklime as the main raw material, and then mixed with the appropriate amount of gypsum and a certain amount of cinder and other aggregates, according to a certain proportion.
The raw materials mixing, the quicklime hydration, the mixture is wheel milled, static pressure forming by hydraulic high static pressing machine, and it can be steamed curing under normal pressure or high-pressure steam.
The compressive strength of autoclaved fly ash bricks is generally high, reaching 20 MPa or 15 MPa, at least 10 MPa, and can withstand the freeze resistance requirements of 15 freeze-thaw cycles.
In addition, fly ash brick is a potentially active hydraulic material that can continue to produce hydration reactions in a humid environment, which is beneficial to the improvement of strength.
Steam-Free and Burn-Free Fly Ash Bricks – Natural Curing
Cement-containing fly ash bricks: cement is the main cementitious material, fly ash, slag, stone powder, sand, gravel, after a certain ratio.
After molding, it is made by natural curing, the strength can reach 15Mpa, and the production process is simple. It is very suitable for low-investment fly ash brick production projects.
Clay-containing bricks – burned at high temperatures.
Fly ash and industrial slag and clay as the main raw materials, 52% of fly ash, 8% of industrial waste furnace slag, and 40% of clay, then mixed by a mixer, extruded by a vacuum clay brick machine, dried, then high temperature Burned.
The principle is that the fly ash and the industrial slag are dehydrated quickly, and the combustible component has high characteristics, so that the Half-finished bricks generate internal combustion.
When the clay bricks burning, it can be used with less or no coal, achieving energy saving, saving land and utilizing waste. The product has the characteristics of bending resistance, compression resistance, lightweight, heat preservation, sound insulation and good appearance. The compressive strength reaches 16.68 MPa.
What Is Fly Ash Brick Machine?
Going into the manufacturing or construction business is a bold step. But you would need certain materials to make the process easier for you. Most manufacturers have plans to extend the scope or simply want to reduce costs.
So, what is a brick machine and what does it do? The machine facilitates the manufacturing of fly ash bricks by reducing human inputs. In the place, it uses the built-in properties to facilitate the production process.
- Static Press Brick Machine to Produce Steam Curing Fly Ash Brick
- Vibrate Concrete Block Machine to Produce Steam-Free Fly Ash Brick
- Vacuum Clay Brick Machine to Produce Burned Clay Fly Ash Brick
In addition, it does most of the work with little supervision. In that case, the machine is capable of feeding on raw materials. Mixing materials and forming fly ash bricks.
Thus, the role of brick machine does not stop at saving costs. It also scales the production of bricks by working on automation in most cases.
What Is Fly Ash – Why Should I Use It?
Traditional manufacturing and building processes have over time, evolved and took a different shape. Fly Ash Brick (FAB) is one of the leading reinventions in building materials. It promises to stand the test of time.
Let us look at the meaning of Fly Ash and the importance of utilizing it in making bricks.
Fly ash is a coal combustion product that comprises fine particles of burned fuel. These are used to enhance the manufacturing of different products.
Fly ash is composed of different particles, including calcium oxide, aluminum oxide, and silicon dioxide. These are placed in different categories and later used for different purposes.
Some of the uses include stabilization of soft soil, and for concrete production. The latter use (concrete production) has been prominent in recent years. It’s used by manufacturers in different sectors of the economy, including infrastructures and industries.
The importance of fly ash bricks is because of the roles it plays in the manufacturing process. For instance, it is a viable substitute material for Portland. It is also viable in the production of bricks.
Aside from that, fly ash bricks help in boosting the manufacturing of building units. This is common when they combine with water gypsum and cement.
What are the Other Materials of Fly Ash Bricks?
Quicklime is the main raw material of autoclaved fly ash bricks: the function is to stimulate the activity of fly ash, so that the bricks have certain physical and mechanical properties.
- Calcium Content: The effective calcium content is as high as possible, and the lime with high calcium content is used in the production of fly ash bricks, and the cost is reduced.
- Fast Hydration: It can shorten the cycle of the digestion process of the mixture and improve production efficiency.
- The digestion temperature is increased as much as possible: the high temperature helps the bricks to increase their strength before the steam curing treatment.
What is Lime Hydration?
Lime Hydration: The lime will hydrolyze after it meets water, produce calcium hydroxide, release heat, and expand the volume by 2-3 times. This process is called quicklime digestion.
The Proportion of Lime for Fly Ash Bricks: The amount of lime incorporated is related to the steam curing conditions, the type and fineness of the fly ash. Generally, when high-pressure curing is used, the amount of lime incorporated is less than that of normal-pressure curing.
The smaller the fineness of fly ash particles, the smaller the amount of lime incorporation, and vice versa.
Production practices have shown that the most effective lime content ranges from 8% to 12%.
Gypsum: Gypsum plays an role in accelerating hydration reaction, increasing crystallization of hydrates, and improving the early strength of bricks, especially the flexural strength, in the production of autoclaved fly ash.
Fineness requirement: 88um sieve, the sieve residue is not more than 15%.
Calcium sulfate content: ≥ 65%.
Source of gypsum: natural gypsum, and industrial waste gypsum (desulfurized gypsum) such as dihydrate gypsum (gypsum), hemihydrate gypsum (building gypsum), or anhydrite.
Gypsum dosage: It is mainly determined according to whether the fly ash brick meets the expected strength.
What is the Formula of Bricks?
As a manufacturer, you may be looking for a way to mix fly ash. Fly ash is not the only ingredient used for the production of building units.
Rather, it is important to combine it with other components, including water and fly ash to get the bricks you want.
The point to note here is that three (3) methods are used for the production. These are the standard method and the other is termed the “Profitable Mixing Ratio”.
The classification is simple: the first follows the standard quality of making fly ash bricks. The second is ideal when you have few materials to spare.
Now, the first method uses quicklime for the manufacturing of bricks. The second method uses hydrated Lime for the manufacturing of fly ash bricks. The third is for the production of fly ash bricks using cement instead of lime and gypsum.
Join us as we look at the formula of mixing fly ash bricks.
- The Normal Ratio Quicklime Fly Ash Bricks – Steam Curing
The materials or ingredients needed here are Gypsum, Sludge Lime, Fly Ash, and Sand/Stone Dust. They are classified in the following ratio:
|Quarry Dust or Sand||25%|
- For Hydrated Lime Fly Ash Bricks – Steam Curing
The ingredients are the same as the first. However, Sledge Lime would be substituted with Hydrated Lime. Here is the ratio:
|River Sand or Stone Dust||18-27%|
- Fly Ash Bricks Manufacturing Using Cement – Natural Curing
In this case, the materials would be primarily focused on cement rather than on gypsum and lime. This is the formula:
|Stone Dust or River Sand||30-40%|
The Others Formula for Fly Ash Bricks
Use 2% Gypsum for Autoclave Steam Curing Fly Ash Bricks
|Quarry Dust or Sand||20%|
Uses 1% Gypsum and No Sand for Autoclave Steam Curing Fly Ash Bricks
Uses Clay or Soil for Burned Fly Ash Bricks
|Clay or Soil||40%|
|Cinder or Slag||8%|
How to Produce Fly Ash Bricks – The Process
Autoclave Bricks Machine Operate Principle
It is now time to get to work. Manufacturing bricks using a fly ash manufacturing machine could be easy.
It can also turn out to be a herculean task. This is tenable when you lack the idea of producing the bricks.
Read the guide below to have a better understanding of producing bricks.
Hydraulic Static Pressure Brick Machines
The manufacturing process of bricks is similar to making concrete blocks.
In the same manner, hydrated lime powder is added to the fly ash. Then gypsum is mixed with it.
Proceed to feed the fly ash, quarry dust, hydrated lime, and gypsum into a pan mixer. You would then add the required proportion of water for intimate mixing. Ensure that the mixture is in the right proportion (consult the tables above).
After mixing, the mixture is then shifted to the ash brick making machine for processing. Ideally, the mixture is transferred to the hopper of the machine through the conveyor belt.
This would then be moved to the cavity. This is where the fly ash brick press machine would press the materials until they take a specific shape.
Thee would then be an erection. This would bring out the manufactured bricks in front of the machine.
Steam Curing Fly Ash Bricks
The manufactured autoclaved fly ash bricks have two ways for curing.
Differences of Fly Ash Bricks Steam Curing Method.
|Steaming Method||Saturated Steam Pressure/MPA||Curing Temperature/℃||Maintenance Equipment||Cost of Equipment||Product Quality||Product Cost|
|0.1||95-100||Steam Curing Room||Low||Meet the Standard||High (More Lime Consumption)|
|High Pressure||0.9 ~ 1.6||174-200||Autoclave||High||Better Performance||Low (Less Lime Consumption)|
