   Name one method of determining moisture content.

   Hint

   It's a slow but common method.

3. 3.

   What is the primary purpose of the Moisture Content Test?

   • To determine the density of aggregates
   • To measure the water present in aggregates
   • To assess the shape of aggregates

   Hint

   Think about why knowing water levels is essential in concrete.

4. 4.
