Summer Concreting Tips – Build Better with Unity Cement
June 30, 2025
Why Hot Weather Concreting Matters
As temperatures soar above 40°C in many parts of India, summer poses unique challenges for construction projects. The intense heat doesn’t just make work uncomfortable—it directly impacts the performance and durability of concrete.
At Unity Cement, we recognise the critical role that temperature plays in concrete quality. Our summer concreting guide is designed to help builders, engineers, and contractors build stronger and smarter, even under extreme conditions.
The Impact of Heat on Concrete: Key Risks
Concrete undergoes an exothermic reaction while setting. In hot weather, this internal heat combines with high ambient temperatures, accelerating water evaporation and reducing concrete workability.
Common problems in summer concreting include:
- Fast loss of workability, leading to mix imbalance
- Early shrinkage cracks on the surface
- Reduced final strength, even if initial setting is fast
- Durability issues like water leakage and structural fatigue
- Increased maintenance costs over time
Why Unity Cement is Ideal for Summer Concreting
Unity Cement offers specialized cement solutions that perform exceptionally well in high temperatures. Our PPC (Portland Pozzolana Cement) and PSC (Portland Slag Cement) are engineered to reduce the heat of hydration, ensuring more stable concrete behavior during hot weather.
Benefits of Unity PPC & PSC in summer:
- Lower internal temperature rise during setting
- Better resistance to thermal cracking
- Improved long-term strength
- Enhanced durability in harsh environments
Best Practices for Concreting in Hot Weather
1. Material Storage & Preparation
- Store cement bags in shaded, dry areas
- Use cold or chilled water for mixing
- Pre-chill aggregates or use ice flakes where possible
- Keep mixing time short to avoid heat buildup
2. Concrete Placement & Timing
- Pour concrete during early morning or evening hours
- Keep formwork and reinforcement cool with water sprays
- Use covered transport systems to prevent temperature rise
- Apply evaporation retarders or plastic sheets immediately after pouring
3. Curing: The Final Crucial Step
- Start curing as soon as the surface is set
- Use mist spraying, ponding, or wet coverings like hessian cloth
- For large pours, consider chemical curing compounds
- Protect against sudden temperature shifts when removing shuttering
Expert Tips for Durable Summer Construction
To enhance the effectiveness of your concrete mix, Unity Cement recommends:
- Using polycarboxylate ether-based admixtures
- Avoiding excessive cement content
- Incorporating shrinkage control fibers (under expert supervision)
- Ensuring accurate water-cement ratio at all times
