1. What is the Sand Calculation Formula?

The sand calculation formula determines the quantity of sand needed for brick wall mortar based on the mortar volume and cement:sand ratio. It accounts for the density of sand (1600 kg/m³) and standard mortar composition factors.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Mortar volume — Typically 0.05–0.07 m³ per m² of wall
• 1.33 — Standard factor for mortar composition
• Ratio — Cement:sand ratio (e.g., 6 for 1:6 ratio)
• 1600 — Density of sand in kg/m³

Explanation: The formula calculates the sand portion of mortar based on the specified ratio, then converts volume to weight using sand density.

3. Importance of Accurate Sand Calculation

Details: Proper sand calculation ensures correct mortar consistency, prevents material wastage, and helps in accurate cost estimation for construction projects.

4. Using the Calculator

Tips: Enter mortar volume in cubic meters (typically 0.05–0.07 m³ per m² of wall) and the cement:sand ratio (e.g., 6 for 1:6 ratio). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical mortar volume per m² of wall?
A: Typically 0.05–0.07 m³ per m² of brick wall, depending on brick size and joint thickness.

Q2: What is the standard cement:sand ratio?
A: For brick walls, 1:6 is common (1 part cement to 6 parts sand).

Q3: Why is sand density 1600 kg/m³?
A: This is the average density of dry sand used in construction calculations.

Q4: Does this account for wastage?
A: No, you should add 5-10% extra to account for wastage during mixing and application.

Q5: Can I use this for other mortar types?
A: This is specifically for brick wall mortar. Different applications may require adjusted ratios.
