Concrete Proportion Calculator
Calculate concrete mix proportions for your construction projects. Determine cement, sand, aggregate quantities and costs for different concrete grades.
Step 1: Concrete Mix Design
Understanding Concrete Mix Ratios
Standard concrete mixes are expressed as cement:sand:aggregate ratios. M25 (1:1:2) is common for structural work, while M15 (1:2:4) is used for non-structural applications.
Step 2: Material Costs
About Concrete Materials
Cement binds the mix, sand fills voids and provides workability, while aggregate provides strength. Prices vary by region and quality. Always add 5-10% for waste and spillage.

Material Cost Breakdown
Concrete Mix Formula
Concrete Volume = (Cement + Sand + Aggregate) × (1 + Waste%)
To calculate material quantities: Multiply each component ratio by total volume, then add waste percentage. Costs are calculated by multiplying quantities by material prices.
