1. What is Concrete Ratio?

The concrete ratio refers to the proportion of cement, sand, and aggregate used in a concrete mix. It's typically expressed in parts (e.g., 1:2:3 means 1 part cement, 2 parts sand, and 3 parts aggregate).

2. How Does the Calculator Work?

The calculator uses the following formulas:

Where:

• \( Cement \) — Parts of cement in the mix
• \( Sand \) — Parts of sand in the mix
• \( Aggregate \) — Parts of aggregate in the mix

Explanation: The calculator determines the ratio between components and calculates what percentage each component represents in the total mix.

3. Importance of Concrete Ratio

Details: The correct concrete ratio is crucial for achieving the desired strength, workability, and durability of the concrete. Different ratios are used for different applications (foundations, slabs, etc.).

4. Using the Calculator

Tips: Enter the parts of cement, sand, and aggregate you plan to use in your mix. The calculator will show you the ratio and percentage composition. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a standard concrete mix ratio?
A: A common ratio is 1:2:3 (cement:sand:aggregate) for general purpose concrete. For foundations, 1:3:6 is often used.

Q2: How does water factor into the ratio?
A: Water is typically not included in the ratio but is crucial for workability. The water-cement ratio (usually 0.4-0.6) affects strength.

Q3: What if I use more aggregate?
A: More aggregate generally increases strength but reduces workability. The mix may become harsh and difficult to place.

Q4: Can I use this for mortar mixes?
A: Mortar typically doesn't contain aggregate (just cement and sand), but the same calculation principles apply.

Q5: How precise do the measurements need to be?
A: For small batches, measure precisely. For larger batches, slight variations have less impact on the final product.
