The water-cement ratio of a concrete mix is defined as the ratio of
Correct answer: B. Mass of water to mass of cement
- A. Volume of water to volume of cement
- B. Mass of water to mass of cement
- C. Mass of cement to mass of aggregate
- D. Volume of cement to volume of water
Explanation
The water-cement ratio is normally calculated by dividing the mass of mixing water by the mass of cement. It is not based on the volumes of these materials.

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.
