The Air Entrainment Ratio Calculator is a valuable tool for assessing the proportion of air incorporated into a concrete mix. Air entrainment is crucial in concrete for improving its resistance to freezing and thawing, enhancing workability, and reducing the risk of segregation. This calculator helps determine the air entrainment ratio by comparing the volume of air to the volume of concrete, expressed as a percentage.

**Formula**

To calculate the air entrainment ratio, use the following formula:

The air entrainment ratio (R) is calculated by:

R = (Va / Vc) * 100

Where:

**R**is the air entrainment ratio in percentage.**Va**is the volume of air in cubic meters.**Vc**is the volume of concrete in cubic meters.

**How to Use**

**Volume of Air (Va):**Enter the volume of air present in the concrete mix, measured in cubic meters.**Volume of Concrete (Vc):**Enter the total volume of concrete, measured in cubic meters.- Click the "Calculate" button to determine the air entrainment ratio.
- The result will be displayed as a percentage in the designated field.

**Example**

Assuming:

- Volume of Air (Va) = 0.05 m³
- Volume of Concrete (Vc) = 1.0 m³

After entering these values and clicking "Calculate," the air entrainment ratio will be 5.00%, indicating that 5% of the concrete's volume is air.
