1:3Basic Formula Used in a Mortar Mix Calculator
The basic formula is:
Mortar Volume = Masonry Volume × Mortar PercentageMortar typically occupies:
20% to 30%of brick masonry volume.
Brick Mortar Mix Calculator Example
Suppose you are constructing a brick wall.
| Item | Value |
|---|---|
| Wall Length | 20 ft |
| Wall Height | 10 ft |
| Wall Thickness | 9 inches |
Step 1 – Calculate Wall Volume
Convert thickness:
9 inches = 0.75 feetVolume:
20 × 10 × 0.75
= 150 cubic feetStep 2 – Estimate Mortar Volume
Assume mortar occupies 25%.
150 × 0.25
= 37.5 cubic feetFinal result:
Mortar Required = 37.5 Cubic Feet
A Brick Mortar Calculator performs this instantly.
Mortar Calculator for Brickwork
A Brick Mortar Calculator helps estimate:
- Mortar volume
- Cement bags
- Sand quantity
- Brick joint mortar
This is extremely useful for:
- Brick walls
- Boundary walls
- Residential houses
- Commercial masonry
Mortar Calculator for Blockwork
Concrete blocks require mortar for joint filling.
A Mortar Calculator helps estimate mortar requirement for:
- AAC blocks
- Hollow blocks
- Solid concrete blocks
Blockwork usually consumes less mortar than brick masonry.
Mortar Calculator for Plastering
Plastering requires accurate mortar estimation to avoid wastage.
A Mortar Calculator helps determine:
- Cement quantity
- Sand quantity
- Mortar thickness
- Plastering area
Example of Plaster Mortar Calculation
Suppose:
| Item | Value |
|---|---|
| Wall Area | 1000 sq ft |
| Plaster Thickness | 12 mm |
Convert thickness:
12 mm = 0.039 ftVolume:
1000 × 0.039
= 39 cubic feetAdd 30% dry volume increase:
39 × 1.3
= 50.7 cubic feetFinal result:
Mortar Volume = 50.7 Cubic Feet
A Mortar Calculator estimates this instantly.
Cement Quantity in Mortar
Cement quantity depends on mortar ratio.
For 1:6 mortar:
Total parts:
1 + 6 = 7Cement proportion:
1/7If total mortar volume is 50.7 cubic feet:
50.7 ÷ 7
= 7.24 cubic feet cementApproximate cement bags:
7.24 ÷ 1.25
≈ 5.8 bagsCement Required = 6 Bags
A Mortar Mix Calculator automates this process.
Sand Quantity in Mortar
For 1:6 mortar:
Sand proportion:
6/7Sand quantity:
50.7 × 6/7
= 43.45 cubic feetSand Required = 43.45 Cubic Feet
Why Dry Volume is Increased
Dry materials occupy more volume than wet mortar.
Typically:
30% to 35%extra volume is added during calculation.
