For accurate proportioning of concrete ingredients, batching by mass is generally preferred to batching by
Correct answer: B. Volume
- A. Moisture correction
- B. Volume
- C. Absolute volume
- D. Specific gravity
Explanation
Mass batching gives more reliable control over the quantities of cement, water and aggregate. Volume batching can introduce errors because aggregate volume changes with moisture and bulking.

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.
