Size of steel bars used for Construction

|

Hello, friends in this post i am going to tell you about some information about size of steel bars. It is not fixed to use the size of steel bars for specific purposes. It depends on the types of construction and purpose of the structure that you are going to construct.

Steel Bars are the construction material which is used to construct structure like building, bridge, RCC road, tower, etc. It is used in Concrete to provide a tensile strength in concrete as the tensile strength of concrete is very less as compared to the compressive strength of concrete.

so, to balance the bearing capacity of concrete structure in both tensile as well as compressive strength we have to use different sizes of steel rods according to design into the concrete. This type of concrete which contains steel rod are known as RCC (Reinforced Concrete Cement).

But we can see generally used diameter of steel bars are for different structure can be given below,

Slabs in the building are constructed using steel bars having a diameter of 8mm, 10mm, 12mm.

In the same way Beams and columns of the building are constructed using 12mm to 25mm diameter of steel bars. But it also depends on the load design and the span of the beam and column.

similarly, the size of steel bars having a diameter 25mm, 32mm and 36mm are used in the hydraulic structures like Dam, Bridge, aqueduct, Reservoiretc.

Finally, we can say that whatever be the structure like column, beam, slab, foundation, RCC wall etc we use the following size of steel bars having diameter.

  • 6mm
  • 8mm
  • 10mm
  • 12mm
  • 16mm
  • 20mm
  • 25mm
  • 32mm
  • 36mm

Also, we can find the steel bars having diameter 5mm but they are used for the non-structural purposes.

But if required the constructors should order to the factory to construct the desired diameter of steel according to their design of the structure. So it may be, 40mm, 45mm, 50mm, 60mm, etc.

So, friends, I hope you got some knowledge about the different size of steel bars used in construction.

Types of Foundations / Footings in Building Construction

Image
  Hi guys this is Structures Explained, and in this blog we will be learning about various kinds of footings, used in a building construction. Foundations are a part of Sub structure which are below ground level and transfer all kinds of loads on the structure, to the ground. Various factors play a role in selecting the suitable type of Foundation for the structure such as, type of structure, condition of the soil at the location of construction, other surrounding structures, water table below, property limits and many more depending on site conditions. Once the foundations are laid for a structure, it is very difficult or impossible to repair or inspect it for structural damages. Hence it is very important to select and design appropriate foundations. Foundations are broadly divided in two categories. First is Shallow Foundations and second is Deep Foundations. Shallow Foundations are nearer to the surface where as Deep foundations as the name suggests, are embedded deeper in eart...

Difference Between PCC, DPC and RCC in Civil Engineering

Image
  In this article I have described about what is PCC, DPC and RCC in civil engineering. These terms are often used in civil engineering. So, I have given some pointwise explanation with their meaning, function and uses. But you have to read carefully to understand it better for practical life in construction. The different between pcc, rcc and dpc are given below:- what is PCC DPC and RCC in civil engineering What is PCC? It stand for Plain concrete cement. This is the mixture of cement, sand , aggregate and water only. Reinforcement is not provided in concrete while construction. It can not be used for column, beam, slab etc which have to bear load or tensile force. It can bear compressive load only so, it can be used for making floor, retaining wall, road etc. What is RCC? It stand for  Reinforcement  concrete cement. This is the mixture if cement, sand , aggregate,water as well as steel rods. It can be used for column, beam, slab etc which have to bear load or compress...

Slump and Compression test of concrete

Image
  Concrete Slump Test This test is performed to check the consistency of freshly made concrete. The slump test is done to make sure a concrete mix is workable. The measured slump must be within a set range, or tolerance, from the target slump.                                               Tools and apparatus used for slump test (equipment): Standard slump cone (100 mm top diameter x 200 mm bottom diameter x 300 mm high) Small scoop Bullet-nosed rod (600 mm long x 16 mm diameter) Rule Slump plate (500 mm x 500 mm)   Workability   of concrete is mainly affected by consistency i.e. wetter mixes will be more workable than drier mixes, but concrete of the same consistency may vary in workability. It can als...
