Question

The compressive strength of concrete determined from $15cm\times 15cm$ @ cylinder as compared to that from $15cm\times 30cm$ @ cylinder is

• A. More
• B. Less
• C. Equal
• D. Dependant on mix propagation

Answer 1

The correct option is A More

The compressive strength of concrete determined from 15 cm x 15 cm @ cylinder as compared to that from 15 cm x 30 cm @ cylinder is more because the slenderness effect will be more in the 15 cm x 30 cm cylinder specimen resulting in early failure as compared to 15 cm x 15 cm cylinder specimen.
