What is Brick Quantity?
The Brick Quantity Calculator estimates standard bricks and mortar materials needed for masonry wall construction based on wall dimensions and opening deductions.
Formula
Net Wall Volume = (Length × Height × Thickness) - Opening Deductions
Bricks Count = Net Wall Volume ÷ Modular Brick Volume with Mortar (0.00198 m³) × (1 + Waste %)
Variables Explanation
- Wall L, H, T: Wall length, height, and thickness in meters.
- Openings: Subtracted area of doors/windows.
- Modular Brick with Mortar: 0.20m × 0.10m × 0.10m = 0.002 m³ (500 bricks/m³).
How to Calculate
1. Enter wall length, height, and thickness.
2. Deduct door and window opening volumes.
3. Specify wastage percentage (typically 5%).
4. Review total bricks count, cement bags, and sand tonnage.
Worked Example
Wall: 15m long, 3m high, 0.23m thick (9-inch wall). Total Volume = 10.35 m³.
Net Bricks = 10.35 × 500 = 5,175 bricks.
With 5% Waste: 5,175 × 1.05 = 5,434 Bricks.
Mortar Volume (30%): 3.105 m³ → Dry Mortar (× 1.33) = 4.13 m³.
Cement (1:6 ratio): 12 Bags | Sand: 7.9 Tons.
Practical Construction & Project Controls Use
Procurement of clay bricks or AAC blocks, masonry labor subcontracts, and building quantity takeoffs.
Understanding the Result
Provides complete material requirement list for wall masonry execution.
Limitations & Assumptions
Uses standard modular brick dimensions (190mm × 90mm × 90mm). Non-standard traditional bricks require custom dimensions.
Frequently Asked Questions
How many standard bricks are in 1 cubic meter of wall masonry?
Standard modular brickwork contains approximately 500 bricks per cubic meter including 10mm mortar joints.
What percentage of brickwork volume is mortar?
Mortar occupies approximately 25% to 30% of total masonry wall volume.
Why is 1.33 used as dry mortar volume factor?
Dry sand and cement shrink by approximately 33% when mixed with water to form mortar paste.
What is a typical mortar mix ratio for brick walls?
1:6 (1 part cement to 6 parts sand) for load-bearing walls; 1:4 for half-brick 4.5-inch partition walls.
How do AAC blocks differ from clay bricks in quantity estimation?
AAC blocks are much larger (600×200×150mm), requiring only ~55 blocks per m³ compared to 500 clay bricks.
