In a concrete mix, increasing the water content without changing the cement content usually causes
Correct answer: D. Higher workability and lower potential strength
- A. Lower workability and higher strength
- B. Higher strength and reduced capillary porosity
- C. Lower workability and lower bleeding
- D. Higher workability and lower potential strength
Explanation
Additional water generally improves workability, but it raises the water-cement ratio and leaves more capillary pores after hydration. Consequently, potential strength and durability usually decrease if the mix is properly compacted in both cases.

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.
