What is the free moisture content for the provided aggregate weights: SSD= 1350g, Dry= 1300g, Wet=1400g?

What is the free moisture content for the provided aggregate weights: SSD= 1350g, Dry= 1300g, Wet=1400g?

• A. 3.75%
• B. 3.70%
• C. 4.00%
• D. 3.85%

Answer: (B)

To determine the free moisture content of the aggregate, the formula used is: \[ \text{Free Moisture Content (\%)} = \frac{\text{Weight of Wet Aggregate} - \text{Weight of Dry Aggregate}}{\text{Weight of Dry Aggregate}} \times 100 \] In this case, the given weights are: - Weight of Wet Aggregate = 1400g - Weight of Dry Aggregate = 1300g First, we calculate the difference between the wet weight and the dry weight: \[ 1400g - 1300g = 100g \] Next, we can plug this value into the formula: \[ \text{Free Moisture Content (\%)} = \frac{100g}{1300g} \times 100 \] Calculating the ratio: \[ \frac{100}{1300} = 0.076923 \] Now, multiply by 100 to convert it into a percentage: \[ 0.076923 \times 100 = 7.6923\% \] This percentage is not the free moisture content directly; we need to look specifically for the decimal equivalent related to what is typically provided in the context of the options listed (often

To determine the free moisture content of the aggregate, the formula used is:

[ \text{Free Moisture Content (%)} = \frac{\text{Weight of Wet Aggregate} - \text{Weight of Dry Aggregate}}{\text{Weight of Dry Aggregate}} \times 100 ]

In this case, the given weights are:

• Weight of Wet Aggregate = 1400g

• Weight of Dry Aggregate = 1300g

First, we calculate the difference between the wet weight and the dry weight:

[ 1400g - 1300g = 100g ]

Next, we can plug this value into the formula:

[ \text{Free Moisture Content (%)} = \frac{100g}{1300g} \times 100 ]

Calculating the ratio:

[ \frac{100}{1300} = 0.076923 ]

Now, multiply by 100 to convert it into a percentage:

[ 0.076923 \times 100 = 7.6923% ]

This percentage is not the free moisture content directly; we need to look specifically for the decimal equivalent related to what is typically provided in the context of the options listed (often
