The Hindustan RMC calculator is India’s most complete free tool for Ready Mix Concrete estimation. Whether you’re a civil engineer, contractor, or site supervisor — this tool calculates your RMC volume in cubic meters, estimates cement, sand, and aggregate quantities, and helps you select the right RMC grade (M15 to M50) for your project. The Hindustan RMC calculator also works as an RMC mix design calculator, concrete volume calculator, and RMC cost estimator for slabs, columns, beams, and footings — all in one free tool. No app download needed.
| Material | Per m³ | Total (your volume) | Unit |
|---|
| Grade | Mix Ratio (C:S:A) | Strength (N/mm²) | Cement (kg/m³) | Best For |
|---|---|---|---|---|
| M15 | 1:2:4 | 15 | 250 | PCC, levelling, lean concrete |
| M20 | 1:1.5:3 | 20 | 320 | Slabs, beams — most common grade |
| M25 | 1:1:2 | 25 | 380 | Structural RCC, columns |
| M30 | Design Mix | 30 | 400 | High load columns, raft foundations |
| M35 | Design Mix | 35 | 430 | Bridges, industrial structures |
| M40 | Design Mix | 40 | 460 | Prestressed concrete, flyovers |
| M50 | Design Mix | 50 | 530 | High performance, metro structures |
Choose between RMC Volume Calculator (for finding how many m³ you need), RMC Mix Ratio Calculator (for material quantities per IS 10262), or RMC Cost Estimator for budgeting.
In the Volume tab, choose your element type — slab, column, beam, footing, or wall. Select the RMC grade recommended by your structural engineer. M20 is standard for most residential work.
Enter length, width, and thickness/depth in meters. For multiple similar elements (e.g., 8 columns), enter the count in “Number of Elements.” Add wastage factor based on site complexity.
Instantly see your total RMC volume in m³, cement bags required, sand and aggregate quantities, water litres, and number of RMC trucks needed — ready to share with your Ready Mix supplier.
Dry material volume = Wet volume × 1.54 (bulkage factor)
Cement (bags) = [Dry vol × (C/(C+S+A))] ÷ 0.035 m³ per bag
Sand (m³) = Dry vol × S/(C+S+A) | Aggregate (m³) = Dry vol × A/(C+S+A)
Example (M20 slab 6×4×0.15m): Vol = 3.6 m³ → Dry = 5.54 m³ → Cement = 31.6 bags, Sand = 0.69 m³, Agg = 1.38 m³
RMC truck capacity: Standard transit mixer = 6 m³ | Mini = 4 m³ | Large = 8–10 m³
Pre-configured for slabs, columns, beams, footings, and walls — not just a generic L×W×H calculator. The Hindustan RMC calculator adapts dimension labels to your element type for fast, error-free input.
The Mix Ratio tab uses IS 10262 guidelines — the same standard followed by Hindustan RMC, ACC, UltraTech, and other ready mix plants in India. Get cement, sand, aggregate, and water quantities per cubic meter.
The Cost tab calculates total RMC project cost including base rate, pumping charges, transit/delivery, and GST — giving you a realistic procurement budget before calling your RMC supplier.
The Hindustan RMC calculator is your complete pre-order planning tool — from calculating the exact RMC volume in m³ for any structural element, to getting IS 10262-based mix design quantities, to estimating the total RMC cost with GST and pumping charges. Whether you’re building a house slab, casting columns, or planning a large commercial pour — bookmark this free Hindustan RMC calculator and share it with your contractor, engineer, and site team.
