1. What is Paver Bedding Mix Ratio?

The paver bedding mix ratio refers to the proportion of cement to sand used to create a stable base for pavers. Common ratios are 1:3 or 1:4 (cement:sand) depending on the required strength and application.

2. How Does the Calculator Work?

The calculator uses simple ratio mathematics:

\[ \text{Sand} = \text{Cement} \times \left(\frac{\text{Sand Part}}{\text{Cement Part}}\right) \]

Where:

1:3 ratio means 1 part cement to 3 parts sand
1:4 ratio means 1 part cement to 4 parts sand

Explanation: The ratio determines the strength and workability of the bedding mix. 1:3 provides stronger but less workable mix, while 1:4 is standard for most applications.

3. Importance of Proper Mix Ratio

Details: Correct ratio ensures proper bonding, durability, and load distribution for pavers while preventing cracking or shifting over time.

4. Using the Calculator

Tips: Select desired ratio (1:3 for heavy traffic areas, 1:4 for standard applications) and enter amount of cement to calculate required sand.

5. Frequently Asked Questions (FAQ)

Q1: Which ratio should I choose?
A: Use 1:3 for driveways or high-traffic areas, 1:4 for patios and walkways.

Q2: How much water should be added?
A: Add water gradually until the mix holds together when squeezed but isn't soupy.

Q3: Can I add other materials?
A: Some professionals add lime (10% of cement volume) for improved workability.

Q4: How thick should the bedding layer be?
A: Typically 1-1.5 inches thick after compaction.

Q5: How long does it take to set?
A: Initial set occurs in 24 hours, full strength develops over 28 days.
