M20 कङ्क्रिट मिक्स रेसियो

M20 is a standard concrete grade used in building foundations, slabs, columns, and more. It provides a good balance between strength and cost for residential and light commercial structures.

What is the M20 Mix Ratio?

The mix ratio for M20 concrete is: 1:1.5:3 → 1 part Cement : 1.5 parts Sand : 3 parts Aggregate

This means for every 1 kg (or bag) of cement, you'll need 1.5 kg of sand and 3 kg of coarse aggregate.

How Much Cement is in M20?

For 1 cubic meter of M20 concrete:

• Cement required: ≈ 8 bags (1 bag = 50 kg)
• Sand required: ≈ 0.42 m³
• Aggregate required: ≈ 0.84 m³
• Water: ≈ 160 liters (0.5 water-cement ratio)

*Exact values may vary based on moisture, bulking, and site conditions.

Volume Formula

Use the dry volume formula: Wet Volume × 1.54 (to account for voids)

Example: For 1 m³ wet concrete → 1.54 m³ dry volume

Use Cases of M20

• Residential building slabs and footings
• Beams and columns of G+1 or G+2 buildings
• Light commercial RCC structures
