Benefits of Prestressed Concrete

What is Prestressed Concrete?

Here we are talking about what is prestressed concrete and why it is widely used these days. We will also see the advantages and where the prestressed concrete is used.

The prestressed concrete has the ability to eliminate the traction forces of the concrete by adding artificial compression tensions before applying exterior loads. And also assure that when it is superimposed, the total permanent tensions should lie between the limits which the material can bear indefinitely. This technique is widely used in modern days to building all the architectural and engineering projects. As this method has many benefits.

There are many advantages of using prestressed concrete which is given below.

Structural Strength

With the use of the prestressed technique in concrete gives the maximum strength by providing an internal compression force which counteracts the traction force produced by loads of the structural elements.

The durability of the Construction

One of the principal benefits of the prestressed beams is it eliminates the crack from all the load stages. There is no crack which means the structure has a greater capacity to withstand loads, impacts, vibration and knocks and minimize the possibility the corrosion in steel which increases the durability of the construction.

Save Money

The tensile concrete allows using of large spans in construction due to the length of pieces which saves material and it is light in weight also. These tensile prestressed beams are using in places like an industrial warehouse which provide better light. It is also used in car parks as these plates allow greater separation. Between loading columns and resulting in saving of material and have large space.

Creative Design

These pieces are easier to use to make any beautiful architectural elements.


The large-scale production of prestressed beams and hollow core slabs provide quality control. High production and minimum production cost which very helps full for large architectural buildings and other projects.


The construction speed is increased by using prestressed concrete. As the many parts of the building can assemble at the same time. And this helps both economically and also save time.

Fly Ash Bricks Composition

Here we provide information about fly ash bricks composition. We describe a process with which material you can manufacture fly ash bricks in less price. The fly ash bricks are made with mainly three different mixing ratios. The price of brick is mainly depending on which fly ash bricks mixing ratio is used.

The cost of fly ash bricks is depending on which composition is used. But whatever fly ash bricks mixing ratio is used and along with that, you have to maintain the quality too.

You can make quality bricks with using best mixing ratio and raw materials as per market requirements. Business is about how to increase profit by using the proper mixing ratio to manufacture fly ash brick at a low cost. Here we explain the 3 very trusted and proven mixing ratios to manufacture fly ash bricks.

  1. Mix Proportion for Fly Ash Brick Manufacturing

  1. Fly Ash – 55 to 60%
  2. Sand or Stone dust – 20 to 25%
  3. Sludge Lime – 15 to 22%
  4. Gypsum – 5%

The material is used to manufacture a fly ash brick is depend on raw material availability and requirement of bricks. It is suggested to use Sludge Lime as it is less expensive than Hydrated Lime. The above mixing ratio is more profitable mixing ratio than below two. The Sludge lime is waste material and costs less than hydrated lime. Sludge lime is usually wet and has lumps and it is used to make quality fly ash bricks.

  1. Mix Proportion for Fly ash brick Manufacturing

Here Hydrated lime is used instead of Sludge lime.

  1. Fly Ash – 57 to 65%
  2. River Sand or Stone dust – 18 to 27%
  3. Hydrated Lime – 9 to 12%
  4. Gypsum – 5%

This mixing ratio is widely used to make quality fly ash bricks. As hydrated lime is easily available this fly ash brick compositions are used by many fly ash brick manufacturers.

  1. Mix Proportion for Fly Ash Bricks Manufacturing with cement instead of gypsum and Lime

  1. Fly Ash 50 – 60%
  2. River Sand or Stone Dust – 30 to 40%
  3. Cement – 8 to 12%

In this mixing ratio, the cement is used instead of gypsum and lime. This ratio is not so used because it is costly and not preferred by entrepreneurs. The price of cement is more than gypsum and lime; thus, this mixing is used only when gypsum and lime are not available.
