Recycling Coal Plant Residue to make Bricks

For the past few decades, we are using fly ash bricks instead of clay bricks because of light weight, high strength, uniformity and less consumption of mortar plastering. These are the common understanding many of you known about fly ash bricks. Let's go deeply about in what way fly ash brick is better than conventional clay bricks.

Clay bricks vs. Fly ash Bricks

Clay bricks are manufactured by using the fertile top soil and are made in sheds. Continuing use of clay bricks will lead to extensive loss of fertile top soil and no fertile land for future agriculture. Deforestation also occurs in search of soil source for clay brick manufacturing. Unlike clay bricks, fly ash bricks are made through a mechanized manufacturing process. So, weather variation does not affect the brick manufacturing process.

Moreover clay bricks have no quality testing facilities, so its quality can't be guessed. Whereas, fly ash bricks are manufactured using pre-programmed hydraulic machines. Bricks from these machines are tested for its quality and durability.

Why Fly ash Bricks?

Fly-ash, an unwanted residue obtained from coal-fired power plants. By adding cement, lime, water, gypsum with fly ash to make bricks. These bricks are lighter and stronger, and they reduce the plastering cost by 30 percent.

Fly-ash bricks are increasingly gaining acceptance in construction because of cost effective, durable, fire and moisture resistant and most importantly environment friendly. With the restriction on the use of clay in manufacturing of bricks, Fly Ash Brick is a best substitute for it.

More details about concrete batching plants can be studied here.

Now let's see about the various types of batching plant available in the market to suit the specific needs of the construction industry.

Transit Mixers:
A transit mixer is a mobile kind of concrete mixing machinery mounted on the truck for transporting concrete or ready mix material from a concrete batching plant directly to the site where it is to be utilized. This type of mixer is highly beneficial for the construction site which requires an instant delivery of fresh concrete mix. This mixer usually occurs while on transport.

Transit mixer provides a fast and convenient way to produce concrete mixtures thereby giving an easy access for concrete mixture forming to the construction contractors. It eliminates the problems of inefficiency in mixing, material wastage, concrete production and delivery delays.

 The transit mixers are therefore popular and are widely used for applications like residential driveways, sidewalks, walkways, patios, pool areas, steps, park areas and retaining wall blocks. However the industrial applications of transit mixers include construction of dams, bridges, canals, high rise apartments, industrial buildings, distant highways, factories and many such infrastructure development projects.

Concrete Pumps:
In some cases when the truck cannot be placed close enough to the site like high rise building or the middle of a long tunnel then the concrete placement is done using concrete pumps. Actually it delivers the concrete mix, where it is inaccessible by normal delivery by truck.
The transportation and delivery of concrete to the site affects their durability. So, concrete pumps must always be at their highest efficiency to avoid this delay. It helps reduce handling and delivery time of the mix which is critical in the durability of concrete.

Proper proportioning of mixed concrete enhances setting, transporting and durability of the concrete.

Ready Mix Concrete Plant:
Ready-mix concrete (RMC) is a type of concrete that is manufactured in a factory or in batching plant according to required specifications, and then delivered to the construction site near the plant. Concrete plant with automated mechanical features provided for low operating cost. This type of ready-mix concrete stays efficient, flexible and cost effective for completing infrastructure developmental projects on time.

The ready mix concrete plant is best for industrial and residential construction projects where speed with quality. Ready mixed concrete, produced under factory conditions, guarantees the highest possible quality. RMC batching plant is advantageous where the requirement of concrete is in less quantity.

Compact Concrete Batching Plant:
Compact concrete batching plant is used to prepare the concrete where the construction project goes on. It is used in the construction site where energy saving is the major requirement. It occupies less space and it is located at the construction site itself, where the concrete can be supplied quickly. Compact concrete batching plant is well known for easy maintenance and low running cost.

Automation and Control:
Modern concrete batch plants employ computer aided control to assist in fast, accurate measurement of input constituents or ingredients, as well as tie together the various parts and accessories for coordinated and safe operation.

The successful completion of a construction project is only possible by selecting the exact batching plant for your construction. If you are interested in starting a new concrete batching plant, don't forget to analyze the following factors:

Effect of Fly Ash on the Properties of Fresh Concrete

The use of good quality fly ash with a high fineness and low carbon content reduces the water demand of concrete and consequently, the use of fly ash should permit the concrete to be produced at lower water content when compared to a portland cement concrete of the same workability.

Benefits of Fly ash used in Portland Cement Concrete:

Use of fly ash in Portland cement concrete (PCC) has many benefits and improves concrete performance in both the fresh and hardened state. Fly ash use in concrete improves the workability of plastic concrete, and the strength and durability of hardened concrete. Fly ash use is also cost effective. When Fly ash is added to concrete, the amount of Portland cement may be reduced.

Mix Design for Fly Ash based Concrete:

Use of Fly ash along with cement helps to provide specific properties like reduced early heat of hydration, increased long term strength, increased resistance to alkali aggregate reaction and sulphate attack, reduced permeability, resistance to the intrusion of aggressive solutions and also economy.

Salient advantage of using fly ash in cement concrete:

• Reduction in heat of hydration and thus reduction of thermal cracks and improves soundness of concrete mass.
• Improved workability / pumpabilty of concrete
• Converting released lime from hydration of OPC into additional binding material - contributing additional strength to concrete mass.
• Pore refinement and grain refinement due to reaction between fly ash and liberated lime improves impermeability.
• Improved impermeability of concrete mass increases resistance against ingress of moisture and harmful gases result in increased durability.
• Reduced requirement of cement for same strength thus reduced cost of concrete.
