In the absolute volume method of concrete mix design, the total volume of ingredients is made approximately equal to the
Correct answer: B. Required volume of fresh concrete
- A. Volume of cement alone
- B. Required volume of fresh concrete
- C. Volume of mixing water
- D. Volume of entrapped air only
Explanation
The absolute volume method proportionates cement, water, aggregates, air and admixtures so that their absolute volumes produce the required concrete yield. The target is the volume of fresh concrete, not the volume of any single ingredient.

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.
