**Question 1: Sieve Analysis for Fine Aggregate**

Below is a sieve analysis for a fine aggregate.

a. Complete the sieve analysis to get the percent passing for all sizes.  
b. Calculate and report the fineness modulus for the system.  
c. Graph your sieve analysis results. Do this using Excel or any other spreadsheet software. You can also use the logarithmic chart that was uploaded on Canvas.  
d. From your grading size distribution analysis, define the type of your graph (Dense, gap, or open graded).  
e. Find the maximum size aggregate for this system.

**Sieve Analysis Data Table**

| Sieve Size, mm | Retained Mass, g | % Retained | Cumulative % Retained | % Passing |
|----------------|------------------|------------|-----------------------|-----------|
| 25             | 0                |            |                       |           |
| 9.5            | 47.1             |            |                       |           |
| 4.75           | 239.4            |            |                       |           |
| 2              | 176.5            |            |                       |           |
| 0.425          | 92.7             |            |                       |           |
| 0.075          | 73.5             |            |                       |           |
| Pan            | 9.6              |            |                       |           |

To complete the table, you need to calculate the following:

1. **% Retained:** Calculate for each sieve by dividing the retained mass by the total mass and multiplying by 100.
2. **Cumulative % Retained:** Add the % Retained values progressively down the table.
3. **% Passing:** Subtract the Cumulative % Retained from 100 for each sieve to find the percentage of aggregate passing through each sieve.

Once the table is complete, you can calculate the fineness modulus (FM), graph the results, and analyze the type of grading.
