🏗️ Concrete Volume Calculator UAE

Concrete is the most used building material in the UAE. From high-rise foundations in Dubai Marina to villa slabs in Abu Dhabi, accurate concrete volume calculation is essential for every project. Getting it wrong means wasting expensive materials or running short mid-pour — both costly mistakes on any UAE site.

Our free Concrete Volume Calculator gives you instant material quantities — cement bags, sand, and aggregate — all adjusted for the UAE standard dry volume factor of 1.54. Whether you are a contractor calculating a residential slab or an engineer specifying a commercial column, this tool saves time and eliminates errors.

How to Use This Calculator

1. Enter the length, width, and depth of your concrete element in metres
2. Select your mix ratio — M20 (1:1.5:3) is standard for most UAE structural work
3. Choose wastage percentage — 10% is recommended for standard pours
4. Click Calculate to instantly get cement bags, sand m3, aggregate m3, and water litres

🇦🇪 UAE Tip: In UAE summer (May to September), temperatures above 40°C accelerate concrete setting significantly. Always request a retarder admixture from your ready-mix supplier and use chilled water in your mix design. Cast concrete during night or early morning hours. Minimum concrete grade for structural elements per Dubai Municipality is M20.

The Formula Explained

Volume = Length x Width x Depth. Dry Volume = Wet Volume x 1.54 (bulking factor). Cement = Dry Volume x (Cement Parts / Total Parts) / 0.0347 (volume of one 50kg bag).

Frequently Asked Questions

What concrete mix is standard for UAE residential slabs?

M20 (1:1.5:3) is standard for most residential slabs and columns in UAE. For foundations in sulfate-rich soil, use SRC cement. For high-rise structural elements, M25 or M30 is typically specified by the structural engineer.

How many 50kg cement bags per cubic metre of concrete?

For M20 mix: approximately 8 bags per m3. For M25: approximately 10 bags. Always add 10% buffer for wastage and spillage when ordering.

Why does UAE use a 1.54 dry volume factor?

When dry materials compact together during mixing, the resulting concrete volume is less than the sum of individual volumes. The factor 1.54 accounts for this reduction, giving you accurate quantities to order from your supplier.
