Question

The approximate ratio of strength of $15cm\times 30cm$ concrete cylinder to that of 15 cm cube of the same concrete is

• A. 1.25
• B. 1.00
• C. 0.85
• D. 0.50

Answer 1

The correct option is C 0.85

Ratio of cylinder strength to cube strength varies from 0.77 - 0.96. Thus 0.85 can be taken as approximate ratio.
