Convert that length into kilograms or Tons. This can be done by multiplying cross section area of steel by its total length by the section tip density of steel which 7850 kg/m3—total steel quantity of column equal to the sum of both main and stirrup steels.
Results show that up to 2% of rust increases the bond strength regardless of concrete strength and diameter of reinforcing bar like the existing data. It might result from the roughness due to rust. As expected, the bond strength increases as the compressive strength of concrete increases and the diameter of the bar decreases.
Hence the correct answer is option A.

Bond Strength of Concrete

The bond strength of concrete refers to the adhesion between the concrete and the reinforcing steel bars (rebars) used in construction. It is important because it ensures that the rebars are effectively anchored in the concrete, which in turn provides the necessary tensile strength to the structure.

Factors affecting Bond Strength of Concrete

There are several factors that affect the bond strength of concrete, including:

- Quantity of Steel: The more steel that is used in the construction, the greater the bond strength between the concrete and the steel. This is because more steel provides more surface area for the concrete to adhere to, and creates more anchor points for the steel to grip the concrete.
- Tensile Strength of Steel: The higher the tensile strength of the steel, the greater the bond strength between the concrete and the steel. This is because stronger steel is able to resist greater forces, which in turn creates a stronger bond with the concrete.
- Grade of Concrete: The higher the grade of concrete used in the construction, the greater the bond strength between the concrete and the steel. This is because higher grade concrete has a lower porosity, which allows it to better grip the steel and create a stronger bond.
- Quantity of Concrete: The more concrete that is used in the construction, the greater the bond strength between the concrete and the steel. This is because more concrete provides more surface area for the steel to grip, which in turn creates a stronger bond.

Conclusion

In conclusion, the bond strength of concrete is affected by several factors, including the quantity of steel, tensile strength of steel, grade of concrete, and quantity of concrete. Of these factors, the quantity of steel has the greatest impact on bond strength, as it provides more surface area for the concrete to adhere to and creates more anchor points for the steel to grip the concrete.
