Question

The compressive strength of $100mm$ cube of concrete as compared to $150mm$ cube is

• A. less
• B. more
• C. equal
• D. less or more as per grade of concrete

Answer 1

The correct option is B more

Compressive strength of $100mm$ cube is greater than the compressive strength of $150mm$ we have a relation as $stress=\frac{force}{area}$
$\because$ $100mm$ cube is having high stress means high internal resistance , means resistance to failure. so it has more compressive strength than bigger one.
