Estimation of Tensile Strength of Concrete
The tensile strength of concrete is estimated using the following formula:
fcr = 0.7 √fck
Where,
fcr = estimated tensile strength of concrete
fck = characteristic compressive strength of concrete
Explanation:
- The estimated tensile strength of concrete (fcr) is calculated using the above formula.
- The value of 0.7 is a constant factor that is multiplied by the square root of the characteristic compressive strength of concrete (fck).
- The characteristic compressive strength of concrete (fck) is the strength of concrete at which not more than 5% of the test results are expected to fall below.
- The formula is based on the assumption that the tensile strength of concrete is proportional to the square root of its compressive strength.
- The formula is widely used in the design of reinforced concrete structures.
Conclusion:
Thus, the correct option is A, i.e., the tensile strength of concrete is estimated by fcr = 0.7 √fck.
