3. Verify the availability and condition of cooling materials.

Placement Process

4. Monitor ambient temperature and adjust concrete temperature accordingly.
5. Ensure continuous pour to avoid cold joints.
6. Utilize thermocouples to monitor internal concrete temperature.

Temperature Monitoring

7. Record temperatures at regular intervals and compare with control plan.
8. Adjust cooling measures based on temperature readings.

Post-Placement Cooling

9. Implement cooling strategies immediately after placement.
10. Monitor surface temperature to ensure uniform cooling.
11. Continue temperature monitoring during the curing period.

Documentation and Review

12. Compile all temperature data and cooling actions for review.
13. Evaluate effectiveness of temperature control measures.

Understanding Mass Concrete and Its Challenges

Mass concrete refers to any large concrete volume where heat generated during hardening is a concern. The primary challenge is managing the thermal gradient between the inner core and the surface, which, if uncontrolled, can lead to cracking. This checklist assists in identifying critical points in the process to ensure uniform curing.
