Concrete Mix Design Calculator
Design a concrete mix by specifying target strength, water-cement ratio, and cement content. Get weights for cement, water, fine and coarse aggregates per cubic yard.
Inputs
ACI 318: residential 3,000–4,000 psi; structural 4,000–6,000 psi; parking/bridges 4,500+ psi
ACI 318 Table 19.3.3.1: severe exposure max 0.40 w/cm; moderate 0.45; general 0.50 max
Results
Cement
564 lb/yd³
Estimated Strength
7,502 psi
How to Use This Calculator
- Enter target compressive strength (f'c in psi) and water-cement ratio (w/c).
- Set cement content (lb/yd³) and select coarse aggregate type.
- Review Cement, Water, and aggregate proportions per cubic yard.
- Use ACI 211.1 proportions as a starting point and adjust based on trial batches.
