1. What Are Mix Ratios?

Mix ratios specify the proportions of different materials needed for construction mixtures. For mortar (used in bricklaying and plastering), it's typically cement to sand. For concrete, it's cement to sand to aggregate.

2. How Does the Calculator Work?

The calculator uses standard mix ratios:

Explanation: The calculator multiplies your cement amount by each part of the ratio to determine how much of other materials you need.

3. Importance of Proper Mixing

Details: Using the correct ratio ensures the mixture has the right strength, workability, and durability for its intended use.

4. Using the Calculator

Tips: Select your mix type (mortar or concrete), choose a standard ratio, and enter how much cement you plan to use. The calculator will show the corresponding amounts of other materials needed.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between mortar and concrete?
A: Mortar is cement+sand used as glue between bricks/blocks. Concrete includes aggregate (gravel) for structural applications.

Q2: When to use 1:4 vs 1:6 mortar?
A: 1:4 is stronger (for load-bearing walls), 1:6 is more economical (for non-load-bearing partitions).

Q3: What does "1 bag of cement" mean?
A: Standard cement bags are typically 50kg or 94lb (US). The calculator works with any unit as long as you're consistent.

Q4: Can I adjust these ratios?
A: These are standard ratios. For special applications, consult an engineer.

Q5: How much water should I add?
A: Water is typically 20-25% of cement weight, but adjust for desired consistency (stiffer for some applications).
