Detailed Solution
Download Solution PDFExplanation:
- The water-cement ratio influences the workability and consistency of concrete.
- A lower water-cement ratio typically results in a more rigid mixture, which requires a higher-frequency vibrator to properly consolidate the mix.
- On the other hand, a higher water-cement ratio (more fluid mixture) may require a lower-frequency vibrator to ensure proper compaction and avoid segregation.
