The main advantage of steam curing concrete in precast production is that it
Correct answer: B. Provides high early strength
- A. Eliminates the need for cement
- B. Provides high early strength
- C. Prevents every type of shrinkage
- D. Makes aggregate grading unnecessary
Explanation
Steam curing raises the temperature and moisture available for hydration, allowing precast units to achieve useful early strength quickly. It does not eliminate cement or remove the need for proper mix proportioning.

About Concrete Technology
Concrete technology covers cement, aggregates, water and admixtures, including their properties, proportioning and effect on fresh and hardened concrete. It explains workability, water-cement ratio, setting, hydration, strength, durability, curing, mix design and common defects, while distinguishing segregation and bleeding from general loss of workability.
