1. What is Sharp Sand?

Sharp sand, also known as concrete sand or grit sand, is a coarse sand used in construction for making concrete and mortar. It has larger, more angular particles than builder's sand.

2. How Does the Calculator Work?

The calculator uses the standard formula:

Where:

• \( Area \) — Surface area to be covered (square meters)
• \( Depth \) — Depth of sand layer (meters)
• \( 1600 \) — Density of sharp sand (kg/m³)

Explanation: The calculation determines the weight of sharp sand needed to cover a specific area at a given depth.

3. Importance of Accurate Calculation

Details: Accurate sand calculation ensures you purchase the right amount for your project, avoiding waste or shortages that could delay work.

4. Using the Calculator

Tips: Measure your area accurately in square meters. Typical sand depths vary by application: 50mm for paving, 100mm for concrete slabs.

5. Frequently Asked Questions (FAQ)

Q1: How much does sharp sand cost?
A: Prices vary by location and quantity, typically £30-£50 per tonne in the UK, $40-70 per ton in the US.

Q2: What's the difference between sharp sand and building sand?
A: Sharp sand has larger, angular grains for better concrete strength. Building sand is finer for bricklaying.

Q3: How should I store sharp sand?
A: Keep it dry and covered. Wet sand can compact and become difficult to work with.

Q4: Can I use this calculator for other sand types?
A: Only if they have the same density (1600 kg/m³). Some sands may be denser or lighter.

Q5: How many bags will I need?
A: Standard bulk bags hold about 800kg. Divide your total by 800 to get the number of bulk bags needed.
