Concrete quality control - field note 086

While pouring the 200,000 m³ of concrete for the Hyderabad Outer Ring Bridge, we noticed unexpected slump variation.

• Implement a centralized batching schedule with real-time slump measurement.
• Use a mobile app to log mix ratios and operator IDs.
• Conduct daily laboratory tests for compressive strength.

Achieving 95% mix consistency prevented costly rework and kept the 4‑week schedule on track.
