5.4.10.3. Infrared/Microwave Method

Try these first

1. 1.

   What is the primary purpose of the Infrared/Microwave Method?

   Hint

   Think about the relationship between moisture and concrete mix design.

2. 2.

   Why is rapid moisture measurement important at construction sites?

   Hint

   Consider the consequences of not adjusting the mix in time.

3. 3.

   What does the Infrared/Microwave Method measure?

   • Air quality
   • Moisture content
   • Temperature

   Hint

   Think about why moisture would be important in construction.

4. 4.

   True or False: The Infrared/Microwave Method is only suitable for laboratory conditions.

   • True
   • False

   Hint

   Consider where construction happens.

5. 5.

   Given that you are on-site and have the Infrared/Microwave Method at hand, but no traditional moisture meter, outline a plan for measuring moisture in aggregate and adjusting the concrete mix accordingly.

   Hint

   Think of the steps: measure, calculate, and adjust.

6. 6.

   Discuss how the variability of aggregate materials might impact the effectiveness of the Infrared/Microwave Method.

   Hint

   Reflect on the properties of aggregates.
