Concrete Mix Calculator
Calculate the amount of cement, sand, gravel, and water needed for your concrete mix. Perfect for slabs, footings, walls, and other construction projects.
Step 1: Project Dimensions
Concrete Volume Formula
Volume = Length × Width × Thickness. Convert thickness from inches to feet by dividing by 12. For irregular shapes, calculate sections separately.
Step 2: Mix Specifications
Water-Cement Ratio
A typical water-cement ratio is 0.45-0.6. Use less water for stronger concrete, more for workability. Always follow manufacturer recommendations.

Concrete Mix Formula
Materials Calculation
Concrete mix ratios are expressed as Cement:Sand:Gravel. For a 1:2:3 mix, you need 1 part cement, 2 parts sand, and 3 parts gravel by volume. Add water according to desired consistency.
