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

Cement
564 lb/yd³
Estimated Strength
7,502 psi
Water254 lb/yd³
Fine Aggregate (Sand)1,315 lb/yd³
Coarse Aggregate1,817 lb/yd³

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.
