Reason Why Builder Prefer Fly Ash Brick over Normal Red Brick

Of course fly ash bricks. Fly ash bricks are frequently used for different kinds of construction purposes. It is often preferred due to their strength and moisture resistant features.

These bricks are made from fly ash residue that is created when specimens of coal are burned for generating electricity.

Nowadays most engineers, building professionals and workers choose fly ash bricks because they’re much stronger than other types of bricks.

One of the most distinct advantages of using them is that it is hardly affected by changing weather conditions.

The chemical components of these bricks make them highly resistant to moisture. That is why water particles will hardly even penetrate the surface of these bricks.

So, my suggestion is to pick Fly ash bricks for quality building construction.

What are the pros and cons of fly ash bricks?

Fly ash is the residue that is left from burning coal. It is somewhat like a glass powder and is fine in nature.

Advantages:-

·         Fly ash by mixing efficiently with the concrete mix will replace Portland cement which in turn aid in making big savings in concrete material prices.

·         It is an environmentally-friendly solution.

·         It improves the strength over time and also offers greater strength to the building.

·         The long-term strengthening action of flash results in lower bleed channels and also reduces the permeability.

·         The reduced permeability of concrete by using fly ash also helps in keeping aggressive composites on the surface where the damaging action is reduced.

·         It is highly resistant to sulfate, mild acid, & water.

·         It effectively combines with alkalis from cement & thereby prevents the destructive expansion.

·         It helps in reducing the heat of hydration. The pozzolanic reaction in between lime and fly ash would significantly generate less heat and thereby prevents thermal cracking.

·         It effectively binds salts and free lime that can create efflorescence. The lower permeability of fly ash concrete will efficiently reduce the effects of efflorescence.

Disadvantages:

·         Poor quality often has a negative impact on the concrete. It increases the permeability, and thereby damages the building.

·         Some fly ash, that are produced in power plant are usually compatible with concrete. Whereas some needs beneficiation.

·         Therefore, it is very much important to use only high quality fly ash. It prevents negative effects on the structure of the building.

Is there some way in which we can add roughness to fly ash bricks?

I guess you doubt over brick-to-brick gripping with mortar due to its smoother outer walls. If this is the case, then we cleared off our doubts too. The fly ah bricks come with threaded outer walls.

All sides of a brick are marked with threads or slots. So neither gripping of mortar with bricks would have doubts nor gripping of plastering.

This is a more personalised idea. Perhaps you won’t find such bricks with most of fly ash bricks supplier.

What are the effects of excessive lime content in fly ash bricks?

A fly ash brick is made with various combinations of materials and by using many technologies.

With the latest technologies and right binders in right proportion which suits the ash chemistry, the Fly ash brick specifications far overtake the conventional ones.

How can the normal curing time for fly ash bricks be reduced?

Natural curing can be upto fifteen days long. During monsoons it is not possible. There’re three main methods of increasing speed of curing.

The land requirement for storing is also negligible compared to natural curing where you would require large piece of land.

You can use an autoclave in which low pressure steam is used. This is the fastest method.

What is the market for fly ash bricks?

India is a market for two hundred fifty billion bricks equivalent for walking material alone. A few years ago this was dominated by red burnt clay bricks.

Moreover they’re environmental friendly and have better thermal conductivity. Henceforth the market is huge.

What is the investment required for a small scale plant?

It totally depends upon production capacity, i.e., per day production of bricks. You can start with thousand bricks to one crore bricks per day.

Generally small scale brick manufacturing plants have capacity between four thousand to ten thousand bricks per shift of eight hours.

For producing four thousand to five thousand bricks per shift, you will require minimum 6-7 lakhs investment except land.

Is setting up a fly ash brick manufacturing plant profitable?

If a power plant sets up a Brick making plant, the cost of making bricks can be as low as Rs 2 to 2.5 per brick including depreciation & finance cost.

This is for a fully automated plant which has very little manual intervention.

In the United States, the barriers to entry would be very high. Most US brick is decorative clay and many current brickyards were established in the early 1900’s.
