Summary

This video script demonstrates the process of testing moisture content in sand using a moisture analyzer. The procedure involves preparing three 25-gram sand samples, setting the analyzer to 110°C, and running a 10-minute test. Throughout the process, the temperature, time, and moisture percentage are monitored. After the test concludes, the final weight of the sample is recorded. This detailed, step-by-step guide ensures accurate moisture content measurement and serves as a valuable instructional resource for laboratory procedures.

Takeaways

• 😀 The testing involves measuring the moisture content of sand using a moisture analyzer.
• 😀 Three specimens, each weighing 25 grams, are prepared for the moisture content testing.
• 😀 Essential equipment includes a moisture analyzer, 25 grams of sand per sample, and a moisture analyzer pen.
• 😀 The moisture analyzer is powered on by pressing the on/off button.
• 😀 Temperature is set to 110°C using the F1 button to increase and the F2 button to decrease the temperature.
• 😀 After the temperature reaches 110°C, the enter button is pressed to confirm.
• 😀 The drying time is set to 10 minutes, adjusted with the F1 and F2 buttons.
• 😀 Before placing the sample in the moisture analyzer, the 'Enter' key is pressed to begin calibration, and the display should show zero.
• 😀 The sample is placed in the moisture analyzer, and the lid is closed to begin the test.
• 😀 After the 10-minute testing period, the final weight of the sand is recorded, and the moisture content is calculated as a percentage.

Q & A

How is the calibration of the moisture analyzer done before inserting the samples?

Before inserting the samples, the moisture analyzer is calibrated by pressing 'Enter', which resets the display to zero.

What happens after the samples are inserted into the moisture analyzer?

Once the samples are inserted, the lid of the moisture analyzer is closed, and the 'Enter' button is pressed to start the moisture content testing process.

How is the moisture content percentage displayed during the test?

The moisture content percentage is displayed every minute, showing the progress of the test over time.

What should be done once the test reaches the 10-minute mark?

After 10 minutes, the 'CF' button is pressed to finalize the test, and the final weight of the sample is recorded.

What is the final weight of the sample after the moisture content test?

The final weight of the sample is 24.18 grams after the moisture content test.
