🏗️ CONCRETE MIX RATIO 1:2:3

🔹 Mix Proportion (by volume):

• 1 part Cement

• 2 parts Sand

• 3 parts Gravel

🔹 Approximate Materials for 1 m³ of Concrete:

• Cement: 7–7.5 bags (50 kg each)

• Sand: 0.51 m³

• Gravel: 0.77 m³

🔹 Key Quality Tips:

✅ Use clean sand, gravel, and water.

✅ Maintain the correct water-cement ratio.

✅ Compact and cure concrete properly.

✅ Use an approved mix design for structural work.

⚠️ Note: A 1:2:3 nominal mix does not automatically guarantee M20 strength. Use a verified mix design and applicable standards for structural concrete.
