Quality control of concreting in hot temperature

1. Management of Materials
   • Aggregates shall be stock-piled in shade.
   • Regular sprinkling of water to aggregate.
   • Arrangement for circulation of cold air in aggregates.
   • Using cold water (up to 5^oC)
   • Low heat cement can be used.
   • Retarding admixtures are also helpful in delaying the setting process.
2. Management of Concreting Work:
   • Scheduling the concreting work in evening (but with sufficient lighting)
   • Use of more masons for quickly finishing the work.
   • Transporting the concrete in deep containers.
   • Covering of concrete with moist materials as early as possible.
3. Curing of Concrete:
   • The concrete shall be cured with cold water.
   • The surface shall be continuously made wet either by ponding, or using water absorbing materials in surface like cloth, jute, sand, etc.
   • If possible, shade shall be maintained on the concrete.
