Cement Mix Calculator
Estimate cement, sand, and aggregate quantities from wet concrete volume and a declared nominal mix ratio.
Formula
Dry volume = wet volume*dry factor; component volume = dry volume*component ratio/sum of ratios.
About the Cement Mix Calculator
Estimate cement, sand, and aggregate quantities from wet concrete volume and a declared nominal mix ratio.
How the Cement Mix Calculator Works
The entered dry-volume factor expands wet volume for voids and handling; the declared 1:sand:aggregate ratio allocates that dry volume before cement mass and bags are estimated.
Formula
Dry volume = wet volume*dry factor; component volume = dry volume*component ratio/sum of ratios.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.

Accuracy and Limitations
Mix design, moisture, grading, density, strength, and local codes require project-specific engineering. Nominal ratios are estimates, not a certified batch design.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
