Concrete Mix Calculator
Calculate the exact amounts of cement, sand, aggregate, and water needed for your concrete mix. Perfect for DIY projects and construction planning.
Step 1: Project Dimensions
Understanding Concrete Volume
Concrete volume is calculated based on the dimensions of your project. Standard concrete mixes require approximately 2,400 kg per cubic meter. Always add a waste factor to account for spillage and uneven surfaces.
Step 2: Mix Ratio & Materials
About Concrete Mix Ratios
The mix ratio (e.g., 1:2:3) represents the proportion of cement, sand, and aggregate. A standard mix is 1:1.5:3. Water-cement ratio affects strength and workability – typically 0.4 to 0.6.

Material Cost Analysis
Concrete Mix Formula
Volume × Density × Ratio = Material Quantity
Concrete material quantities are calculated by multiplying the total volume by the density of each material and the mix ratio. Standard concrete density is approximately 2,400 kg/m³.
