1. What is Mortar Calculation?

Mortar calculation determines the quantities of cement and sand needed for brickwork construction based on the mortar volume and mix ratio. Accurate calculation helps in proper material estimation and cost control.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• Mortar volume — Total volume needed (in cubic meters)
• Ratio — Cement to sand ratio (e.g., 6 for 1:6 ratio)
• 1.33 — Dry mortar factor (accounts for voids)
• 1440 — Cement density (kg/m³)
• 1600 — Sand density (kg/m³)

3. Importance of Accurate Calculation

Details: Proper calculation prevents material wastage, ensures structural integrity, and helps in budgeting. Too much cement makes mortar brittle, while too little weakens the bond.

4. Using the Calculator

Tips: Enter mortar volume in cubic meters and the ratio number (e.g., 6 for 1:6 mix). The calculator will provide cement and sand quantities in kilograms.

5. Frequently Asked Questions (FAQ)

Q1: What is a standard mortar ratio for brickwork?
A: Common ratios are 1:4 to 1:6 (cement:sand) for general brickwork, with 1:6 being typical for most applications.

Q2: Why multiply by 1.33?
A: This accounts for the dry volume of mortar being about 33% more than the wet volume due to voids and shrinkage.

Q3: How do I estimate mortar volume?
A: As a rough guide, 0.03 m³ mortar is needed per 1 m² of 115mm thick single-leaf brick wall.

Q4: Can I use this for other mixes?
A: This is specifically for cement-sand mortar. Other mixes (like lime mortar) require different calculations.

Q5: What if my sand density differs?
A: The standard is 1600 kg/m³, but you can adjust the final sand quantity proportionally if your sand density differs.
