Here is an steel quantity calculator that will help users estimate the quantity of steel required for different types of structures based on the concrete volume and the steel weight per cubic meter as specified in the table below.

Use the dropdown menu for selecting the type of structure and enter the for the quantity of concrete in cubic meters, and a click the button get the quantity of steel.

Enter the type of structure and the quantity of concrete in cubic meters:

Quantity of Steel (kg):

## Why we use Steel in concrete members?

Steel reinforcement is used in concrete to increase the tensile strength and ductility of the material. Concrete is a strong material in compression, but it is weak in tension. By adding steel reinforcement to the concrete, the tensile strength of the overall structure can be increased, allowing it to better withstand forces such as bending, shearing, and tension.

There are several benefits to using steel reinforcement in concrete, including:

• Increased strength and stability: Steel reinforcement can significantly increase the strength and stability of a concrete structure, making it more resistant to external forces such as wind, earthquakes, and heavy loads.
• Ductility: Steel has a high degree of ductility, meaning that it can stretch and deform without breaking. This allows the steel reinforcement to absorb some of the energy from external forces, helping to prevent the concrete from cracking.
• Improved durability: Concrete structures that are reinforced with steel are less prone to cracking and deterioration over time, making them more durable and long-lasting.

There are various sizes of steel rebars available, ranging from 8 mm to 32 mm in diameter. The size of the rebar is typically determined by the size and type of the concrete structure, as well as the loads that the structure is expected to bear.

## Factors Affecting quantity of reinforcement required

There are several factors that can affect the required quantity of reinforcement in a concrete structural member, including:
