Question

As per IS code of practice, concrete should be cured at :

• A. ${35}^{\circ }C$
• B. ${25}^{\circ }C$
• C. ${27}^{\circ }C$
• D. ${50}^{\circ }C$

Answer 1

The correct option is C ${27}^{\circ }C$

As per BIS (IS:516) the compressive strength of a concrete mix is determined by curing concrete cubes (150 mm) for 28 days at temperature of ${27}^{\circ }C(\pm 2^{\circ }C)$
