About This Tool
Design the perfect concrete mix for your slab, beam, or column. The Concrete Mix Calculator breaks down the required volume of concrete into its constituent materials: Cement, Fine Aggregate (Sand), and Coarse Aggregate (Metal/Gravel). Simply select the grade of concrete (e.g., M20 for slabs, M15 for floors) and the target volume. The tool uses standard IS code mix ratios to give you the exact weight and volume of materials needed. This tool has become indispensable for construction professionals across India, from small contractors to large construction firms. It accounts for industry-standard specifications and local building codes, ensuring your estimates are accurate and reliable. The calculator helps prevent costly mistakes like material shortages mid-project or excessive wastage that impacts your budget. Whether you're bidding on a project, planning a renovation, or managing a large construction site, this tool provides the precision you need for successful project execution. It saves hours of manual calculations and reduces the risk of human error in critical construction planning. Our algorithms are optimized for performance, ensuring instant results even for complex calculations. We are committed to providing free, high-quality tools to help you be more productive.
How to Use This Tool
Select Grade
Choose the concrete grade (e.g., M20 - 1:1.5:3).
Enter Volume
Input the total wet volume of concrete needed.
Calculate
View the breakdown of Cement, Sand, and Aggregate.
Key Features
- Standard Grades: Pre-loaded ratios for M5, M7.5, M10, M15, M20, M25.
- Dry Volume Logic: Automatically adds 54% bulkage for dry volume conversion.
- Water Cement Ratio: Estimates water requirement for the mix.
- Unit Flexibility: Get results in bags, kgs, cft, or cubic meters.
Frequently Asked Questions
What is M20 grade?
M20 is a mix ratio of 1:1.5:3 (Cement:Sand:Aggregate), achieving a characteristic strength of 20 N/mm² after 28 days. It is commonly used for RCC slabs.
Why multiply by 1.54?
Dry materials contain air voids. To get 1 cubic meter of wet concrete, you need approximately 1.54 cubic meters of dry materials.
