In a concrete mix, moisture present on the surface of wet aggregates usually requires the batch water to be
Correct answer: B. Reduced by the aggregate surface moisture
- A. Increased by the aggregate surface moisture
- B. Reduced by the aggregate surface moisture
- C. Kept unchanged in every case
- D. Replaced by additional cement
Explanation
Wet aggregates contribute water to the mix, so the added batch water should be reduced to maintain the intended water-cement ratio. Ignoring this correction can produce overly wet concrete and lower strength.

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.
