Question

Consider the following statements:
Curing of concrete by steam under pressure
1. increases the compressive strength of concrete
2. reduces the shear strength of concrete
3. increases the speed of chemical reaction
Which of these statements is/are correct?

• A. 1, 2 and 3
• B. 1 only
• C. 2 and 3 only
• D. 3 only

Answer 1

The correct option is A 1, 2 and 3

Under pressure steam curing increases the speed of hydration of the cement . Curing of concrete by steam under pressure increases the compressive strength whereas reduces the shear stress.
