Question

Normally, the tensile strength of concrete is about ______ of its compressive strength.

• A. \(10\) to \(12\%\)
• B. \(15\) to \(20\%\)
• C. \(20\) to \(25\%\)
• D. \(25\) to \(30\%\)

Hint:

Concrete strength relationship: \[ \boxed{ f_t \approx 0.10\text{ to }0.12\,f_c } \] where \(f_t\) is tensile strength and \(f_c\) is compressive strength.

Answer 1

The Correct Option is A
