Concrete Mix Design Calculator

Input Parameters

Governs all calculation limits and methods
MPa - Cylinder for ACI, Cube for IS/BS
MPa - Required for IS code when f_ck < 60 MPa
Durability control parameter
mm - Workability measure (25-200 mm)
mm - Affects water content and air
Typically 3.10-3.20
SSD condition (2.50-2.80)
SSD condition (2.60-2.90)
For aggregate split (2.2-3.2)
Shape and texture affect water demand
Actual moisture content (0-10%)
Actual moisture content (0-10%)
Fly ash/GGBS replacement (0-50%)
For hot weather rules (10-45°C)
Empirical constant (default: A=10 for ACI)
Empirical constant (default: B=1.5 for ACI)

⚠️ IMPORTANT DISCLAIMER: This calculator provides preliminary mix proportions based on standard code formulations. For actual construction projects, designs must be verified by licensed professional engineers, validated with trial mixes, and adjusted for site-specific conditions. The developers accept no liability for designs derived from this tool.

Enter all required parameters and click "Calculate Mix Design" to see results.
