1. What is the Sharp Sand Cement Calculator?

The Sharp Sand Cement Calculator helps determine the exact quantities of cement and sharp sand needed for mortar mixes based on the area to be covered, thickness of application, and desired mix ratio.

2. How Does the Calculator Work?

The calculator uses standard mortar mix calculations:

Where:

• Area — Surface area to be covered (m²)
• Thickness — Mortar layer thickness (mm)
• Cement Ratio — Part of cement in the mix
• Sand Ratio — Part of sharp sand in the mix

3. Importance of Accurate Mixing

Details: Using the correct ratio of sharp sand to cement is crucial for mortar strength, workability, and durability. Different ratios are used for different applications (bricklaying, rendering, etc.).

4. Using the Calculator

Tips: Measure your area accurately in square meters. Common thicknesses are 10mm for rendering and 12mm for bricklaying. Select the appropriate mix ratio for your project.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between sharp sand and building sand?
A: Sharp sand has larger, angular grains making it better for concrete, while building sand has finer grains for bricklaying.

Q2: What are common mix ratios?
A: 1:3 for high-strength, 1:4 for general purpose, 1:5-1:6 for rendering or plastering.

Q3: How much water should I add?
A: Typically 20-25% of cement weight, but adjust for desired consistency.

Q4: Can I use this for concrete?
A: No, concrete requires different calculations including aggregate.

Q5: How do I convert kg to volume?
A: Sharp sand is ~1.6 ton/m³ (1600 kg/m³), cement ~1440 kg/m³.
