Concrete quality control - field note 044

During the Bengaluru high‑rise project, we managed 120,000 m³ of concrete delivered by CEMEX India. Daily slump tests stayed within ±5 cm, ensuring uniform strength across all floors. The key lesson was to calibrate vibrators before each pour to avoid segregation.

• Standardize slump testing protocol across crews.
• Record test results in a shared dashboard.
• Schedule vibrator maintenance weekly.
• Cross‑check mix design against lab results.
