Quantity of Sand and Cement Calculator for Brick Wall

Mortar Calculation Formulas:

\[ \text{Cement (kg)} = \left[\text{Mortar volume (m³)} \times 1.33 \times \left(\frac{1}{1 + \text{ratio}}\right)\right] \times 1440 \] \[ \text{Sand (kg)} = \left[\text{Mortar volume (m³)} \times 1.33 \times \left(\frac{\text{ratio}}{1 + \text{ratio}}\right)\right] \times 1600 \]

1. What is This Calculator?

This calculator determines the quantity of cement and sand required for brick wall mortar based on the mortar volume and cement-sand ratio.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

Mortar volume — Typically 0.05–0.07 m³ per m² of wall
Ratio — Cement to sand ratio (e.g., 1:4)
1.33 — Dry mortar factor
1440 — Cement density (kg/m³)
1600 — Sand density (kg/m³)

3. Importance of Accurate Calculations

Details: Proper mortar mix ensures structural integrity, workability, and durability of brick walls. Accurate calculations prevent material waste and ensure cost efficiency.

4. Using the Calculator

Tips: Enter mortar volume in cubic meters and cement-sand ratio (e.g., for 1:4 ratio, enter 4). Typical mortar volume is 0.05–0.07 m³ per square meter of wall.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical cement-sand ratio for brickwork?
A: Common ratios are 1:3 to 1:6 depending on the application. 1:4 is standard for general brickwork.

Q2: How do I estimate mortar volume?
A: Multiply wall area by 0.05-0.07 m³/m². For precise calculations, consider brick size and joint thickness.

Q3: Why multiply by 1.33?
A: This accounts for dry volume to wet volume conversion (bulking of sand).

Q4: Can I use this for other masonry work?
A: The principles are similar, but block work may require different ratios and volumes.

Q5: How does weather affect these calculations?
A: In humid conditions, you may need slightly less water, but material quantities remain the same.
