6.11.3. Water Footprint of Concrete

Try these first

1. 1.

   What is the typical water requirement for one cubic meter of concrete?

   Hint

   Think about the range mentioned initially in class.

2. 2.

   What is an admixture in concrete?

   Hint

   Recall how this can change the water footprint.

3. 3.

   What is the typical water footstep for producing one cubic meter of concrete?

   • 100–150 liters
   • 150–200 liters
   • 200–250 liters

   Hint

   Recall the standard range provided.

4. 4.

   True or False: Using water reducers increases the amount of water needed for concrete.

   • True
   • False

   Hint

   What is their purpose?

5. 5.

   A construction project requires a total of 800 cubic meters of concrete. Using the standard water need per cubic meter, what is the total water required? Discuss the best practices to reduce this footprint.

   Hint

   Think about the project scale and methods presented.

6. 6.

   If a project manager wants to reduce water use by 30% for a concrete batch, and the original requirement is 200 liters per cubic meter, how much water should he aim for?

   Hint

   Use percentage reduction to find the new amount.
