Ready Mix Concrete (RMC) has become the cornerstone of modern construction, offering convenience, consistency, and durability. However, achieving the best results depends on proper handling, pouring, and curing techniques. In this blog, we’ll explore essential tips to maintain the quality of RMC on-site and ensure the longevity of your structures.

Best Practices for Handling RMC

1. Inspect Upon Arrival:
   • Verify the delivery ticket for batch details, mix proportions, and slump requirements.
   • Conduct a visual inspection to ensure no segregation or excessive water.
2. Plan for Timely Use:
   • Schedule deliveries to minimize delays and ensure the concrete is used within 90 minutes of batching.
   • Have equipment and manpower ready before the RMC arrives.
3. Protect Against Contamination:
   • Avoid mixing RMC with other materials on-site.
   • Use clean tools and equipment to handle the concrete.

Tips for Pouring RMC

1. Prepare the Site:
   • Ensure the formwork is clean, sturdy, and properly aligned.
   • Apply release agents to the formwork for easy removal after curing.
2. Pour in Layers:
   • Pour RMC in layers of consistent thickness to prevent air pockets and segregation.
   • Use a vibrator to compact the concrete for better strength and durability.
3. Monitor Weather Conditions:
   • Avoid pouring during heavy rain or extreme heat.
   • Use covers or water sprays to maintain appropriate temperatures during hot weather.

Best Practices for Curing RMC

1. Start Curing Immediately:
   • Begin curing within an hour of pouring to prevent surface cracks.
   • Use water sprays, wet burlap, or curing compounds to maintain moisture.
2. Follow the Curing Duration:
   • Allow at least 7 days for curing in normal conditions, and up to 14 days for structures exposed to heavy loads.
3. Protect from Premature Loading:
   • Avoid applying any loads on the concrete until it has achieved the required strength.

Why Maintaining RMC Quality Matters?

Proper handling, pouring, and curing of RMC are critical to:

• Enhancing Structural Integrity: Ensures the building can withstand stress and environmental factors.
• Improving Durability: Prevents cracks, shrinkage, and other defects.
• Saving Costs: Reduces the need for repairs and extends the lifespan of structures.
