Sand Per m2 Brickwork

Sand Calculation Formula:

\[ \text{Sand (kg/m²)} = \left[\text{Thickness (m)} \times 1.33 \times \left(\frac{\text{ratio}}{1 + \text{ratio}}\right)\right] \times 1600 \]

1. What is Sand Per m2 Brickwork?

This calculation determines the amount of sand needed per square meter for brickwork mortar. It's essential for construction planning and material estimation.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Sand (kg/m²)} = \left[\text{Thickness (m)} \times 1.33 \times \left(\frac{\text{ratio}}{1 + \text{ratio}}\right)\right] \times \text{Density (kg/m³)} \]

Where:

\( Thickness \) — Mortar joint thickness (typically 0.01m)
\( ratio \) — Mortar mix ratio (e.g., 6 for 1:6 cement:sand ratio)
\( Density \) — Sand density (typically 1600 kg/m³)
1.33 — Standard factor accounting for mortar volume

Explanation: The equation calculates the volume of mortar needed per square meter and converts it to sand weight based on the mix ratio.

3. Importance of Sand Calculation

Details: Accurate sand estimation helps in budgeting, reduces material waste, and ensures proper mortar consistency for quality brickwork.

4. Using the Calculator

Tips: Enter joint thickness (typically 0.01m), mortar ratio (like 6 for 1:6 mix), and sand density (1600 kg/m³ is standard). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

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

Q2: Why is thickness typically 0.01m?
A: 10mm (0.01m) is the standard mortar joint thickness in most brickwork construction.

Q3: Does sand density vary?
A: Yes, dry loose sand is about 1442 kg/m³ while wet packed sand can be 1682 kg/m³. 1600 kg/m³ is a good average.

Q4: How much extra sand should I account for?
A: It's recommended to add 10-15% extra to account for wastage, uneven surfaces, and other contingencies.

Q5: Can this be used for blockwork?
A: Yes, but blockwork often uses different thicknesses (typically 0.008m) and may require different ratios.
