Fly Ash Utilization in Making Concrete

For concrete manufacturers, the usage of fly ash is their big deal because they use fly ash as a component in the range of 10 to 25% for making concrete mixtures. Because of beneficial use in concrete structures, the Environmental Protection Agency (EPA) is reassessing the classification, storage, disposal and reuse of fly ash to ensure that it is properly managed to minimize potential harm to human health and the environment.

Disposed fly ash from thermal power plant is then used for various purposes. Certain classes of fly ash (wet or dry) are an important component of reinforced concrete, the best composite structural material.

Role of Fly Ash in Concrete Structures

Worldwide, concrete is used in the construction of bridges, buildings, roads and so on. Usage of concrete has never been omitted in the construction project. In simple words, concrete support our infrastructure.

More than 75% of all concrete is made with fly ash. Fly ash is specified for all concrete structures in some states. And the concrete industry is only one of the important entities using this abundant waste material. The reason, recycled fly ash goes into making concrete is it delivers measurable economic and structural benefits. Its worldwide availability, strength, durability and relatively economical cost create a constant demand for fly ash in the construction industry.

 
Beneficial uses of Fly ash

Fly ash is a CCP (Coal Combustion Products) possessing unique characteristics that allow it to be used ton-for-ton as a substitute for portland cement in making concrete. Through the reuse of fly ash, the GHG (green house gas) emissions associated with the production of portland cement are avoided."

Future for Fly ash

After few decades of reducing the environmental impact of portland cement production and providing a means of recycling industrial waste, fly ash and concrete stand strong together.

Environmental Benefits of Fly ash used in Concrete

Use of fly ash in concrete imparts several environmental benefits and thus it is eco-friendly. It saves the cement requirement for the same strength thus saving of raw materials such as limestone, coal etc required for manufacture of cement. Use of fly ash reduces area requirement for pond, thus saving of agricultural land.

We manufacture a wide range of construction machinery like concrete hollow block machines, fly ash brick making machine, tiles making machines, pan mixture, concrete mixture machines, CLC lightweight machine and batching plant system with high quality standard.

Different Types of Concrete Batching Plants

Concrete batching plants combines the ingredients such as sand, water, aggregate, fly ash and cement to form fresh concrete that are used in various construction projects. The main criteria for determining the quality of concrete are its strength and durability. The process of achievement of strength and durability of concrete begins with its production.

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:

• What type of concrete batching plant you require?
• How many types of aggregates you will be using?
• What are the production requirements of your construction project?
• Is the concrete batching plant to be installed on the construction site or on a different land located at a specific distance?
• How many hours in a day you need your concrete batching plant to operate?

We are offering both manual and automatic block making plants in various ranges and also manufacture concrete hollow block machines, fly ash brick making machine, tiles making machines, pan mixture, concrete mixture machines with high quality standard.
